| Reactant | 3-[1-(6,7-Dimethoxy-4-quinazolinyl)-4-piperidinyl]-1,2,3,4-tetrahydro-6-nitro-2,4-dioxoquinazoline | HCID 22923399 | — |
| Product | 3-[1-(6,7-Dimethoxy-4-quinazolinyl)-4-piperidinyl]-1,2,3,4-tetrahydro-1,5-dimethyl-2,4-dioxoquinazoline | HCID 22923496 | 73% |
Reaction Steps
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-5-methyl-2,4-dioxoquinazoline (Compound 100) obtained in Reference Example 11 was used in place of Compound 24. As a result, 226.8 mg (yield: 73%) of Compound 57 was obtained as white crystals.
