Procedure

To a mixture of 2-(4-bromo-3-(trifluoromethyl)phenyl)acetic acid 46-6 (564 mg, 2.0 mmol), 1-(4-(6-aminopyridin-3-yl)piperazin-1-yl)ethanone 111-4 (440 mg, 2.0 mmol) and HATU (798 mg, 2.1 mmol) in DMF (6 mL) was added DIEA (1.04 mL, 6.0 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-(trifluoromethyl)phenyl)acetamide 192-1 (920 mg, 95%). MS m/z 485.1 (M+1).
