Procedure

To a solution of 100 mg (0.20 mmol) N-(6-amino-4-o-tolyl-pyridin-3-yl)-2-(3,5-bis-trifluoromethyl -phenyl)-N-methyl-isobutyramide in 3 ml dichloromethane were added 27 mg (0.21 mmol) N-ethyldiisopropylamine and 70 mg (0.69 mmol) acetic anhydride. After stirring overnight, the solvent was evaporated and the residue was purified by flash-chromatography to give 100 mg (92%) of the title compound as white solid.
