반응 단계
The procedure similar to that described in Example 57 was repeated, except that 1.06 g (3.0 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 4-chloro-6-methoxyquinazoline was used in place of 4-chloro-6,7-dimethoxy-quinazoline. As a result, 154.4 mg (yield: 12%) of Compound 84 was obtained as white crystals.
