실험 절차

A solution of 7-benzyloxy-4-(2,3-dimethylindol-5-yloxy)-6-methoxyquinazoline (2 g, 4.7 mmol) in DMF (120 ml) containing ammonium formate (11 gr, 174 mmol) and 10% palladium on charcoal (200 mg) was stirred for 2.5 hours at ambient temperature. The mixture was filtered, and the filtrate was evaporated under vacuum. The residue was triturated with ether and the solid was filtered, washed with water followed by ether and dried under vacuum at 50° C. to give 4-(2,3-dimethylindol-5-yloxy)-7-hydroxy-6-methoxyquinazoline (1.1 g, 69%).
