YieldReaction ConditionsOperation in experiment
(b) 270 ml of isopropanol and 64.4 g (0.45 mole) of isopropyl 3-aminocrotonate are added to the 2-methoxyethyl 2-(3'-nitrobenzylidene)acetoacetate which has been prepared according to (a) and is moist with isopropanol. The mixture is heated to reflux (83° C.) and kept at this temperature for 24 hours. After cooling to 0° C., the resulting crystals are isolated, washed with 86 ml of isopropanol and sucked dry. 173.2 g of 3-isopropyl, 5-(2-methoxy)-ethyl 1,4-dihydro-2,6-dimethyl-4-(3'-nitrophenyl)-3,5-pyridine dicarboxylate of melting point 122°-127° C. (92percent of theory) are obtained. Thin-layer chromatography on Merck silica gel ready-coated plates (mobile phase: chloroform:acetone:petroleum ether=3:2:5) shows no visible by-products.
