Procedure

More specifically, a dried methylene chloride solution containing 394 mg (1 mmol) of 1,4-dihydro-5-methoxycarbonyl-6-methyl-4-(3-nitrophenyl)-2-phenylpyridine-3-carboxylate, 309 mg (1.5 mmol) of dicyclohexylcarbodiimide and 134 mg (1.1 mmol) of dimethylaminopyridine was stirred for one hour. To this reaction mixture, 157 mg (1.2 mmol) of glycine t-butyl ester was added and the reaction mixture was refluxed for 2 hours. Insoluble components were removed from the reaction mixture by filtration and the reaction mixture was chromatographed on a silica gel column for purification, whereby 508 mg (100%) of the captioned compound was obtained as an oily material.
