반응 단계

The procedure similar to that described in Example 15 was repeated, except that 354.0 mg (1.0 mmol) of 1,2,3,4tetrahydro-1,6-dimethyl-2,4-dioxo-3-(4-piperidinyl)-quinazoline hydrobromide (Compound v) obtained in Example 41 was used, 1,4-dichloro-6,7-dimethoxyphthalazine was used in place of 4-chloro-6,7-dimethoxyquinazoline, and a catalytic amount of potassium iodide was added. As a result, 243.7 mg (yield: 49%) of Compound 76 was obtained as white crystals.
