A solution of 6.2 g of 2,6-dimethyl-3-methoxycarbonyl-4-(3-nitrophenyl)-5-(2-[4-(2-benzyloxyethoxy)-phenyl]ethoxycarbonyl)-1,4-dihydropyridine in 100 ml of ethanol with 0.5 g of 10% palladium on carbon is hydrogenated at 50 psi for 18 h. The mixture is filtered and the filtrate evaporated to afford 2,6-dimethyl-3-methoxycarbonyl-4-(3-nitrophenyl)-5-(2-[4-(2-hydroxyethoxy)phenyl]ethoxycarbonyl)-1,4-dihydropyridine.
