Reaction Steps

To a mixture of 2-(2-fluoro-5-methyl-4-(2-methylpyridin-4-yl)phenyl)acetic acid 191-6 (35 mg, 0.13 mmol), 1-(4-(6-aminopyridin-3-yl)piperazin-1-yl)ethanone 111-4 (30 mg, 0.13 mmol) and HATU (50 mg, 0.13 mmol) in DMF (1.0 mL) was added DIEA (67 uL, 0.4 mmol) and the mixture was stirred at room temperature over night. The reaction mixture was diluted into DMSO and purified by reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(2-fluoro-5-methyl-4-(2-methylpyridin-4-yl)phenyl)acetamide 191. MS m/z 462.2 (M+1). 1H NMR 400 MHz (DMSO-d6) δ10.51 (s, 1H), 8.49 (d, 1H), 8.03 (s, 1H), 7.91 (d, 1H), 7.43 (m, 1H), 7.32 (d, 1H), 7.28 (s, 1H), 7.21 (d, 1H), 7.08 (d, 1H), 3.77 (s, 2H), 3.53 (b, 4H), 3.14 (b, 2H), 3.07 (b, 2H), 2.55 (s, 3H), 2.20 (s, 3H), 2.04 (s, 3H).
