A mixture of ethyl 2-phenyl-4-quinazolinepropionate (4.3 g) and diethylamine (30 cc) is heated to 250°C. for 40 hours. After the mixture is cooled, the excess diethylamine is evaporated off. The residue is chromatographed on silica gel with a cyclohexane/ethyl acetate (1:1 by volume) mixture as eluant. The product (3.2 g) is recovered and recrystallized in isopropyl ether. N,N-Diethyl-2-phenyl-4-quinazolinepropanamide (2.2 g), m.p. 103° C., is obtained.
