Product 1

HCID 229235373-[1-(6,7-Dimethoxy-4-quinazolinyl)-4-piperidinyl]-1-ethoxycarbonylmethyl-1,2,3,4-tetrahydro-6-nitro-2,4-dioxoquinazolineYield 17%

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 bromoacetate was used in place of methyl iodide. As a result, 61.3 mg (yield: 17%) of Compound 6 was obtained as pale yellow crystals.
