実験手順

The procedure similar to that described in Example 40 was repeated, except that 354.0 mg (1.0 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-2-isopropyl-6,7-dimethoxyquinazoline was used in place of 4-chloro-6,7-dimethoxyquinazoline. As a result, 50.3 mg (yield: 10%) of Compound 83 was obtained as white crystals.
