Versuchsvorschrift
The procedure similar to that described in Example 57 was repeated, except that 369.0 mg (1.05 mmol) of 1,2,3,4-tetrahydro-1,6-dimethyl-2,4-dioxo-3-(4-piperidinyl)-quinazoline hydrobromide (Compound v) obtained in Example 41 was used and 7-benzyloxy-4-chloro-6-methoxyquinazoline was used in place of 4-chloro-6,7-dimethoxyquinazoline. As a result, 233.8 mg (yield: 42%) of Compound 87 was obtained as white crystals.
