For treatment for pulmonary fibrosis, phase 2, The lysophosphatidic acid receptor, LPA1, has been implicated as a therapeutic target for fibrotic disorders
Lysophospholipids (LPs), including lysophosphatidic acid (LPA), sphingosine 1-phospate (S1P), lysophosphatidylinositol (LPI), and lysophosphatidylserine (LysoPS), are bioactive lipids that transduce signals through their specific cell-surface G protein-coupled receptors, LPA1-6, S1P1-5, LPI1, and LysoPS1-3, respectively. These LPs and their receptors have been implicated in both physiological and pathophysiological processes such as autoimmune diseases, neurodegenerative diseases, fibrosis, pain, cancer, inflammation, metabolic syndrome, bone formation, fertility, organismal development, and other effects on most organ systems.

BMS-986020, also known as AM152 and AP-3152 free acid, is a potent and selective LPA1 antagonist. BMS-986020 is in Phase 2 clinical development for treating idiopathic pulmonary fibrosis. BMS-986020 selectively inhibits the LPA receptor, which is involved in binding of the signaling molecule lysophosphatidic acid, which in turn is involved in a host of diverse biological functions like cell proliferation, platelet aggregation, smooth muscle contraction, chemotaxis, and tumor cell invasion, among others

Synthesis of Compound 74
Synthetic Route (Scheme XLV)
Compound 74 Compound 74a
 Compound XLV-1 was prepared by the same method as described in the synthesis of compound 1-4 (Scheme 1-A).
 To a solution of compound XLV-1 (8 g, 28.08 mmol) in dry toluene (150 mL) was added compound XLV-2 (1.58 g, 10.1 mmol), triethylamine (8.0 mL) and DPPA (9.2 g, 33.6 mmol). The reaction mixture was heated to 80 °C for 3 hours. The mixture was diluted with EtOAc (50 mL), washed with brine, dried over Na2S04, filtered and concentrated. The residue was purified by column chromatography (PE/EA = 10 IX) to give compound XLV-3 (9.4 g, yield: 83 %). MS (ESI) m/z (M+H)+402.0.
 Compound 74 was prepared analogously to the procedure described in the synthesis of Compound 28 and was carried through without further characterization.
 Compound 74a was prepared analogously to the procedure described in the synthesis of Compound 44a. Compound 74a: 1HNMR (DMSO-d6 400MHz) δ 7.81 (d, J = 8.4 Hz, 2H), 7.41 (d, J = 8.4 Hz, 2H), 7.52 (d, J = 8.4 Hz, 2H), 7.29-7.32 (m, 7 H), 5.78 (q, 1 H), 2.15 (s, 3 H), 1.52 (d, J = 6.0 Hz, 3H), 1.28 (br, 2 H), 0.74 (br, 2 H). MS (ESI) m/z (M+H)+ 483.1.
Development of a Concise Multikilogram Synthesis of LPA-1 Antagonist BMS-986020 via a Tandem Borylation–Suzuki Procedure
The process development for the synthesis of BMS-986020 (1) via a palladium catalyzed tandem borylation/Suzuki reaction is described. Evaluation of conditions culminated in an efficient borylation procedure using tetrahydroxydiboron followed by a tandem Suzuki reaction employing the same commercially available palladium catalyst for both steps. This methodology addressed shortcomings of early synthetic routes and was ultimately used for the multikilogram scale synthesis of the active pharmaceutical ingredient 1. Further evaluation of the borylation reaction showed useful reactivity with a range of substituted aryl bromides and iodides as coupling partners. These findings represent a practical, efficient, mild, and scalable method for borylation.
