Reaction Steps

The procedure is as in Example 7, starting with 2-(4-nitrophenyl)-4-quinazolinepropanoic acid (1.35 g), carbonyldiimidazole (0.82 g) and diethylamine (0.9 cc) in anhydrous tetrahydrofuran (20 cc). After chromatography on silica gel with ethyl acetate as eluant, and recrystallization in ethyl acetate, N,N-diethyl-2-(4-nitrophenyl)-4-quinazolinepropanamide (0.35 g), m.p. 168° C., is obtained.
