Procedure

3 ml of ethyl acetate and 10% palladium carbon were added to 0.100 g (0.170 mmol) of 6-(2-azidoethoxy) methyl-4-(3-chlorophenyl)-5-(3,3-diphenylpropylcarbamoyl)-2-methyl-1,4-dihydropyridine-3-carboxylic acid and stirred at room temperature in hydrogen atmosphere under normal pressure for 40 hours. The reaction mixture was filtered and the filtrate was evaporated under reduced pressure. The residue thus obtained by evaporating the solvent was subjected to Reversed-phase High-performance Liquid Chromatography using octadodecyl group bounded type silica gel as a filler. Then, the obtained substance was eluted with the mixed solvent of water and acetonitrile. The fraction of the object compound was freeze-dried to obtain the title compound as a by-product material of 6-(2-aminoethoxy) methyl-4-(3-chlorophenyl)-5-(3,3-diphenylpropylcarbamoyl)-2-methyl-1,4-dihydropyridine-3-carboxylic acid.
