Procedure
ppm : 1.2 (6H, t, J=7 Hz), 2.4 (3H, s), 3.92 to 4.38 (4H, m), 5.72 (1H, s),7.06 (1H, s), 7.24 to 7.62 (4H, m). (7) To a solution of diethyl 2-methyl-4-(2-methoxyphenyl)-6-diethoxymethyl-1,4-dihydropyridine-3,5-dicarboxylate (447.5 mg) in acetone (7.5 ml) was added 6 N-hydrochloric acid (0.2 ml) and stirred at room temperature for an hour. The resultant mixture was treated in a similar manner to Example 2-4), to give reddish yellow crystals of diethyl 2-methyl-4-(2-methoxypheny)-6-formyl-1,4-dihydropyridine-3,5-dicarboxylate (373.2 mg). The product was recrystallized from a mixture of diethyl ether and n-hexane to give the pure product, m.p. 111° to 112° C.
