Procedure

The procedure of Example 24 is followed using ethyl 2-phenylquinazoline-4-carboxylate (3 g), 4-methylpiperidine (2.95 ml), a 1.6M solution of butyllithium in hexane (15 ml) and tetrahydrofuran (20 ml) as the starting materials. After recrystallisation from ethanol, 4-methyl-1-[(2-phenylquinazolin-4-yl)-carbonyl]-piperidine (1 g), melting at 138° C., is obtained.
