A solution of 7-benzyloxy-4-(4-fluoro-2-methylindol-5-yloxy)-6-methoxycinnoline (500 mg, 1.17 mmol), (prepared as described in Example 3), ammonium formate (740 mg, 11.7 mmol), 10% palladium on charcoal (100 mg) and water (700 μl) in DMF (10 ml) was stirred for 2 hours at ambient temperature. The mixture was filtered on diatomaceous earth and the filtrate was evaporated under vacuum. The residue was triturated with a mixture of ether and pentane (1/1). The solid was filtered, washed with pentane and dried under vacuum to give 4-(4-fluoro-2-methylindol-5-yloxy)-7-hydroxy-6-methoxycinnoline (300 mg, quant.).
