TRIS Salt Formation. Methanol (400 mL) was added to a mixture of 1 (4.0 g, 8.2 mmol) and 2-amino-2-hydroxymethylpropane-1,3-diol (TRIS, 1.0 g, 8.2 mmol). The mixture was heated to 70 °C for 0.5 h. After cooling to room temperature, the solvent was removed in vacuum. The residue was sonicated in dichloromethane (10 mL) and concentrated again. The resulting white solid was dried under vacuum overnight. The crude material was crystallized by slurring the solid residue in a 4:1 mixture of acetonitrile and methanol (5 mL). The mixture was stirred at room temperature for 24 h to give 4-((N-benzyl-8-chloro-1-methyl-1,4-dihydrochromeno- [4,3-c]pyrazole-3-carboxamido)methyl)benzoic acid TRIS salt as a white salt (3.7 g, 73% yield). Melting point: 195.6 °C. 1 H NMR (400 MHz, DMSO): δ 7.92−7.80 (m, 2H), 7.78−7.64 (m, 1H), 7.41− 7.19 (m, 8H), 7.13−7.00 (m, 1H), 5.44 (s, 2H), 5.25−5.14 (m, 2H), 4.61−4.48 (m, 2H), 4.18−4.03 (m, 3H), 3.39 (s, 7H). TRIS OH masked by water peak. LC-MS m/z: 488.0/490.0 (M+H)+ ; chlorine pattern, method 3. RT = 1.58 min. Elemental Analysis calc for C31H33ClN4O7: C 61.00, H 5.36, N 9.15; found: C 60.84, H 5.34, N 9.13.
