Procedure

70 mg (0.3 mmol) of 4-nitrophenyl chloroformate and then 60 μl (0.3 mmol) of diisopropylethylamine are added to a solution of 70 mg (0.25 mmol) of methyl 2(S)-ethoxy-3-[6-(3-methylaminophenyl)pyrid-3-yl]propanoate in 3 ml of dichloromethane. The reaction medium is stirred at room temperature for 2 hours. After addition of water, the reaction medium is extracted with dichloromethane. The organic phase is dried over magnesium sulfate, filtered and evaporated. 110 mg (100%) of methyl 2(S)-ethoxy-3-(6-{3-[methyl(4-nitrophenoxycarbonyl)amino]phenyl}pyrid-3-yl)propanoate are obtained.
