Procedure

The procedure of Example 24 is followed using ethyl 2-phenylquinazoline-4-carboxylate (3 g), pyrrolidine (3 ml), a 1.6M solution of butyllithium in hexane (15 ml) and tetrahydrofuran (25 ml) as the starting materials. After recrystallisation from ethanol, 1-[(2-phenylquinazolin-4-yl)-carbonyl]-pyrrolidine (2.1 g), melting at 153° C., is obtained.
