Reaction Steps

To a solution of N-(3-chloro-2-methylphenyl)-2-[(2S)-pyrrolidin-2-yl]-6-({[2-(trifluoromethyl)phenyl]carbonyl}amino)-1H-benzimidazole-4-carboxamide (Example 71) (26 mg) in THF solution (0.5 mL), was added pyridine (12 μL), and the mixture was stirred under ice-cooling. To the mixture was added acetyl chloride (5.1 μL), and it was stirred at room temperature for 1 hour. To the reaction mixture was added ice water, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified on column chromatography to obtain the titled compound (15 mg) as white powder.
