The resultant residue was diluted with methylene chloride (5 ml) and a 10: 1 mixture (290 ml) of methanol and a saturated aqueous ammonium hydroxide solution was added. The resultant mixture was stirred and heated to 80C for 5 minutes. The solvent was evaporated and the solid residue was suspended in water. The basicity of the mixture was adjusted to pH7 by the addition of dilute aqueous hydrochloric acid solution. The resultant solid was collected by filtration, washed with water and dried under vacuum over phosphorus pentoxide.

The resulting precipitate was collected by filtration, washed with water (5 x 20 ml), ether (5 x 20 ml) and dried to a constant weight in a vacuum oven at 40 C to afford 6,7-dihydroxyquinazolinone (2) (38 g, 100%) as a beige solid: LCMS (retention time = 0.97 min., purity = 98%), ESI+ m/z 179.18 (M+H)+; 'H- NMR (DMSO-d6) delta (ppm) 6.95 (s, 1H), 7.41 (s, 1H), 7.91 (s, 1H), 9.78 (s, 1H), 10.23 (s, 1H), 11.7 (br s, 1H). |
