Product 1

HCID 229235023-[1-(6,7-Dimethoxy-4-quinazolinyl)-4-piperidinyl]-1-ethyl-1,2,3,4-tetrahydro-6-nitro-2,4-dioxoquinazolineYield 67%

Procedure

The procedure similar to that described in Example 1 was repeated, except that 300 mg (0.63 mmol) of Compound 24 was used and ethyl iodide was used in place of methyl iodide. As a result, 213.1 mg (yield: 67%) of Compound 2 was obtained as pale yellow crystals.
