Method for production of quinazolin-4-on derivative |
| abstract |
A quinazolin-4-one derivative represented by the general formula (2), which is useful as an intermediate raw material for production of a medicine, can be produced by reacting an anthranilic acid derivative represented by the general formula (1) (particularly an anthranilic acid derivative selected from anthranilic acid, an anthranilic acid amide and an anthranilic acid ester) with formamide, wherein the reaction is performed under conditions where acetic acid and a base are co-present as catalysts in the reaction solution. In this manner, the derivative can be produced in a high yield without causing any side reaction. |
