| Reactant | 1,2,3,4-Tetrahydro-3-[1-(7-hydroxy-6-methoxy-4-quinazolinyl)-4-piperidinyl]-1,6-dimethyl-2,4-dioxo-quinazoline | HCID 135847591 | — |
| Product | 3-[1-(7-Ethoxycarbonylmethoxy-6-methoxy-4-quinazolinyl)-4-piperidinyl]-1,2,3,4-tetrahydro-1,6-dimethyl-2,4-dioxoquinazoline | HCID 22923438 | 89% |
Reaction Steps
The procedure similar to that described in Example 1 was repeated, except that 500.0 mg (1.12 mmol) of Compound 89 obtained in Example 79 was used in place of Compound 24 and ethyl bromoacetate was used in place of methyl iodide. As a result, 530.0 mg (yield: 89%) of Compound 93 was obtained as white crystals.
