To treat symptomatic tenosynovial giant cell tumor for which surgical resection will potentially cause worsening functional limitation or severe morbidity

Vimseltinib is an orally bioavailable inhibitor of the tyrosine kinase receptor colony stimulating factor 1 receptor (CSF1R; CSF-1R; C-FMS; CD115; M-CSFR), with potential antineoplastic, macrophage checkpoint-inhibitory and immunomodulating activities. Upon administration, vimseltinib targets and binds to CSF1R expressed on monocytes, macrophages, and osteoclasts and inhibits the binding of the CSF1R ligands colony-stimulating factor-1 (CSF-1) and interleukin-34 (IL-34), to CSF1R. This prevents CSF1R activation and CSF1R-mediated signaling in these cells. This blocks the production of inflammatory mediators by macrophages and monocytes and reduces inflammation. By blocking the recruitment to the tumor microenvironment (TME) and activity of CSF1R-dependent tumor-associated macrophages (TAMs), vimseltinib inhibits the immunomodulating activity by macrophages and enhances T-cell infiltration and anti-tumor T-cell immune responses, which inhibits the proliferation of tumor cells. TAMs play key roles in the TME and allow for immune suppression; TAMs promote inflammation, tumor cell proliferation, angiogenesis, invasiveness and survival.

Vimseltinib, sold under the brand name Romvimza, is an anti-cancer medication used for the treatment of tenosynovial giant cell tumor.^[1][2] Vimseltinib is a kinase inhibitor.^[1][2] Vimseltinib is a macrophage colony-stimulating factor receptor antagonist.^[3]

The most common adverse reactions, including laboratory abnormalities, include increased aspartate aminotransferase, periorbital edema, fatigue, rash, increased cholesterol, peripheral edema, face edema, decreased neutrophils, decreased leukocytes, pruritus, and increased alanine aminotransferase.^[2]

Vimseltinib was approved for medical use in the United States in February 2025.^[2][4]

PATENT

vimseltinib is a c-FMS (CSF-IR) and c-KIT dual inhibitor with anticancer and antiproliferative activities, can excite tyrosine protein kinase activity, influence protooncogene transcription, and is widely applied to research of anticancer drugs as an active molecule.

CN105120864B discloses heating the reaction mixture in a sealed tube at 100 ℃ for 2 days. The mixture was then cooled to room temperature, the solids were removed by filtration and the filtrate was concentrated to dryness and purified by silica gel chromatography to give 2- (isopropylamino) -3-methyl-5- (6-methyl-5- ((2- (1-methyl-1H-pyrazol-4-yl) pyridin-4-yl) oxy) pyridin-2-yl) pyrimidin-4 (3H) -one, amorphous form described.

CN113880812a reports another preparation method of Vimseltinib, and a small amount of target product meeting the requirement is finally obtained through a column chromatography purification process. The preparation method has complicated process and is not beneficial to industrialized mass production. There is no mention in this patent of reports on solid or crystalline forms of the compound of formula (I), and the purification process of column chromatography (EA/meoh=120:1 to 100:1) was repeated to give form a.

Example 2: A solution of Example C2 (0.13 g, 0.309 mmol) in DCM (5 mL) was treated portion-wise with mCPBA (0.09 g, 0.37 mmol), stirred at RT overnight, treated with TEA (0.5 mL) and Ν,Ν-dimethylamine HCl salt (500 mg) and stirred at RT for 2 h. The mixture was treated with satd. NaHCO₃, extracted with DCM (2x) and the combined organics were dried over Na₂SO₄, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to obtain 4-methoxy-N,N-dimethyl-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine (60 mg, 47%).

The solution was treated with NaHCO₃ and NaCl, extracted with 1 : 1 THF/EtOAc (3x) and the combined organics were dried over Na₂SO₄ and concentrated to dryness. The material was treated with MeCN (1 mL), allowed to stand at RT and the

resulting solid was collected via filtration to afford 2-(dimethylamino)-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-4(3H)-one (43 mg, 71%). ¹H NMR (400 MHz, DMSO-d₆): δ 11.23 (s, 1 H), 8.73 (s, 1 H), 8.36 (d, J = 5.7 Hz, 1 H), 8.30 (m, 1H), 8.26 (s, 1 H), 7.97 (s, 1 H), 7.51 (m, 1H), 7.23 (d, J = 2.4 Hz, 1 H), 6.62 (br s, 1 H), 3.85 (s, 3 H), 3.12 (s, 6 H), 2.35 (s, 3 H); MS (ESI) m/z: 404.2 (M+H⁺).

The mixture was treated with satd. NaHCO₃, extracted with DCM (2x) and the combined organics were dried over Na₂SO₄, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to obtain N-isopropyl-4-methoxy-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine (63 mg, 47%).
