Reaction Steps

To a solution of (S)-2-(2-amino-1-methylethylamino)-5-cyano-N-(3,4-dimethoxybenzyl)benzamide (99 mg) in dichloromethane (3 mL) was added acetic anhydride (38 mg), and the mixture was stirred for an hour at ambient temperature. The resulting mixture was evaporated in vacuo. The residue was triturated with diisopropyl ether to give (S)-2-[2-(acetamido)-1-methylethylamino]-5-cyano-N-(3,4-dimethoxybenzyl)benzamide (107 mg) as a solid substance.
