Procedure

70 μl (0.45 mmol) of heptylamine are added to a solution of 110 mg (0.25 mmol) of methyl 2(S)-ethoxy-3-(6-{3-[methyl(4-nitrophenoxycarbonyl)amino]phenyl}pyrid-3-yl)propanoate in 3 ml of dimethylformamide. The reaction medium is heated at 80° C. for 3 hours. After addition of water, the reaction medium is extracted with ethyl acetate. The organic phase is dried over magnesium sulfate, filtered and evaporated. The residue obtained is purified by thin-layer chromatography on silica eluted with a 6/4 and then 5/5 heptane/ethyl acetate mixture. 50 mg (50%) of methyl 2(S)-ethoxy-3-{6-[3-(3-heptyl-1-methylureido)phenyl]pyrid-3-yl}propanoate are obtained.
