実験手順

A mixture of methyl 4-amino-5-carbamoyl-2-hydroxybenzoate (5.4 g) and formic acid (50 ml) was heated to reflux for 1 hour. The mixture was evaporated. Toluene (75 ml) was added and the mixture was evaporated. The solid residue was washed with methanol and diethyl ether and dried to give methyl 7-hydroxy-4-oxo-3,4-dihydroquinazolin-6-carboxylate (5.2 g); NMR Spectrum: (DMSOd6) 4.9 (s, 3H), 7.09 (s, 1H), 7.39 (s, 1H), 8.5 (s, 1H).
