Reaction Conditions

Reaction Steps

A solution of 7-benzyloxy-4-chloroquinazoline (2 g, 7.4 mmol), 5-hydroxy-2-methylindole (1.3 g, 8.9 mmol), (prepared as described for the starting material in Example 48), in DMF (20 ml) containing potassium carbonate (1.53 g, 11.1 mmol) was stirred at 80° C. for 3 hours. After cooling, the mixture was poured in portions into ice/water. The precipitate was filtered and washed with water and dried under vacuum. The solid was dissolved in methylene chloride and was purified by column chromatography eluting with ethyl acetate and methylene chloride (1/1) to give 7-benzyloxy-4-(2-methylindol-5-yloxy)quinazoline (2.28 g, 81%).
