Versuchsvorschrift

The procedure is as in Example 1, starting with ethyl 2-(3-methoxyphenyl)-4-quinazolinepropionate (1.2 g) and diethylamine (30 cc). After chromatography on silica gel with a cyclohexane/ethyl acetate (1:1 by volume) mixture as eluant, and crystallization in isopropyl ether, N,N-diethyl-2-(3-methoxyphenyl)-4-quinazolinepropanamide (0.36 g), m.p. 87° C., is obtained.
