Procedure
The procedure of Example 24 is followed using ethyl 2-phenylquinazoline-4-carboxylate (2 g), piperidin-4-ol (1.4 g), a 1.6M solution of butyllithium in hexane (18 ml) and tetrahydrofuran (30 ml) as the starting materials. After recrystallisation from a mixture of methanol and methylene chloride, 1-[(2-phenylquinazolin-4-yl)-carbonyl]-piperidin-4-ol (2.1 g), melting at 209° C., is obtained.
