3-Chlorobenzaldehyde → 5-(3-(Pyridine-3-yl)-2-propene-1-yl) 3-(2-cyanoethyl) 4-(3-chlorophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate

Participants

Reaction Steps

387 mg (2.51 mmol) of 2-cyanoethyl 3-aminocrotonate, 547 mg (2.49 mmol) of (3-(pyridine-3-yl)-2-propene-1-yl) acetoacetate, and 0.285 ml (2.51 mmol) of 3-chlorobenzaldehyde were heated at 80° C. under stirring in 20 ml of 2-propanol overnight. 2-Propanol was evaporated under reduced pressure, and the residue was purified by the silica gel chromatography (chloroform/methanol=100:1) to obtain the title compound.
