HCID 229235093-[1-(6,7-Dimethoxy-4-quinazolinyl)-4-piperidinyl]-1,2,3,4-tetrahydro-1,8-dimethyl-2,4-dioxoquinazolineYield 61%

Procedure

The procedure similar to that described in Example 1 was repeated, except that 300 mg (0.67 mmol) of 3-[1-(6,7-dimethoxy-4-quinazolinyl)-4-piperidinyl]-1,2,3,4-tetrahydro-8-methyl-2,4-dioxoquinazoline (Compound 101) obtained in Reference Example 12 was used in place of Compound 24. As a result, 185.2 mg (yield: 61%) of Compound 59 was obtained as white crystals.
