Potassium Carbonate → HCID 136037979, compound

Participants

Reaction Steps

The yellow solid was triturated with ether and methanol to provide acetic acid [4-(5,7-dimethoxy-4-oxo-3,4-dihydro-quinazolin-2-yl)-phenylcarbamoyl]-methyl ester (112 mg, 37%). To a solution of acetic acid [4-(5,7-dimethoxy-4-oxo-3,4-dihydro-quinazolin-2-yl)-phenylcarbamoyl]-methyl ester (0.23 g, 0.59 mmol) in THF/methanol mixture (3.5 mL/3.5 mL) was added potassium carbonate (0.41 g, 2.95 mmol). The reaction mixture was heated at reflux overnight and the solvent was concentrated under vacuum and diluted with water (60 mL) to obtain a precipitate. The yellow solid was filtered, washed with water (20 mL), methanol and dried under vacuum to provide crude compound. The yellow solid was triturated with ether and methanol to provide the desired compound N-(4-(5,7-dimethoxy-4-oxo-3,4-dihydroquinazolin-2-yl)phenyl)-2-hydroxyacetamide (55 mg, 55%). Selected data: MS (ES) m/z: 356.1; mp 318-319° C.
