Reaction Steps

A solution of 7-benzyloxy-6-methoxy-4-(quinolin-7-yloxy)quinazoline (1.50 g, 3.70 mmol), (prepared as described in Example 196), in trifluoroacetic acid (50 ml) was heated at reflux for 150 minutes. The reaction was concentrated in vacuo and the reaction neutralised with saturated aqueous ammonium hydroxide. The resulting precipitate was filtered, washed with acetone and dried under suction to give 7-hydroxy-6-methoxy-4-(quinolin-7-yloxy)quinazoline (0.90 g, 2.82 mmol, 76%) as a white solid.
