Participants

Reaction Steps

To mixture of N-(6-bromopyridin-3-yl)-1-(4-chlorophenyl)-4-(hydroxymethyl)-1H-pyrazole-3-carboxamide (330 mg, 0.810 mmol) in CH2Cl2 (15 mL) at RT was added methanesulfonyl chloride (0.101 mL, 1.295 mmol) and DIEA (0.283 mL, 1.619 mmol). The resulting mixture was stirred at room temperature over a weekend. The reaction mixture was diluted with H2O, stirred for 5 min and subjected to filtration. The solid collected was dried under vacuum to give Example 17D (340 mg, (99%) as a beige solid. 1H NMR (CDCl3) δ 4.98 (s, 2H), 7.44-7.53 (m, 2H), 7.61-7.72 (m. 2H), 8.06 (s, 1H), 8.20-8.28 (s, 2H), 8.53 (s, 1H), 8.79 (s, 1H). LCMS, [M+H]+=426.9.
