Reaction Steps

To a mixture of 2-(4-bromo-3-methylphenyl)acetic acid 24-5 (100 mg, 0.44 mmol), 1-(4-(6-aminopyridin-3-yl)piperazin-1-yl)ethanone 111-4 (96 mg, 0.44 mmol) and HATU (200 mg, 0.53 mmol) in DMF (2 mL) was added DIEA (230 uL, 1.32 mmol) and the mixture was stirred at room temperature over night. The reaction mixture was partitioned between ethyl acetate and water. The organic phase was washed with brine and dried over Na2SO4 and the solvent was evaporated. The residue was subject to silica gel flash chromatography to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-bromo-3-methylphenyl)acetamide 159-1. MS m/z 431.1 (M+1).
