Reaction Steps

A suspension of (2R)-7-(2-acetoxy-3-(pyrrolidin-1-yl)propoxy)-4-chloro-6-methoxyquinazoline (530 mg, 1.4 mmol) and 4-fluoro-5-hydroxy-2-methylindole (277 mg, 1.68 mmol), (prepared as described for the starting material in Example 237), in DMF (8 ml) containing potassium carbonate (290 mg, 2.1 mmol) was stirred at 90° C. for 2 hours. After cooling, the volatiles were removed under vacuum and the residue was purified by column chromatography eluting with methylene chloride/methanol (95/5) to give (2R)-7-(2-acetoxy-3-(pyrrolidin-1-yl)propoxy)-4-(4-fluoro-2-methylindol-5-yloxy)-6-methoxyquinazoline (580 mg, 81%).
