Reaction Steps

After heating a solution of 15.1 g of 3-nitrobenzaldehyde, 16 g of β-amino-γ-methoxycrotonic acid ethyl ester and 19 g of oxalacetic acid diethyl ester in 60 ml of ethanol under reflux for 12 hours, the mixture is evaporated in vacuo and 2-methoxymethyl-4-(3'-nitrophenyl)-1,4-dihydropyridine-3,5,6-tricarboxylic acid triethyl ester is obtained in almost quantitative yield, in the form of a yellow oil (nD50 =1.5353).
