Versuchsvorschrift

Starting from a mixture of 2-nitrobenzaldehyde (3.02 g), 2-phenoxyethyl acetoacetate (4.44 g), piperidine (272.5 mg) in benzene (10.8 ml) was obtained an oil (8.0 g) of 2-phenoxyethyl 2-(2-nitrobenzylidene)acetoacetate. Thus obtained oil was treated with ethyl 3-amino-4,4-diethoxycrotonate (4.34 g) to give an oil of 2-phenoxyethyl 2-methyl-4-(2-nitrophenyl)-5-ethoxycarbonyl-6-diethoxymethyl-1,4-dihydropyridine-3-carboxylate.
