Reaction Steps
A suspension of 4-chloro-6-methoxy-7-(3-(pyrrolidin-1-yl)propoxy)quinazoline (0.13 g, 0.4 mmol), 5-hydroxy-2-methylindole (74 mg, 0.5 mmol) and potassium carbonate (83 mg, 0.6 mmol) in DMF (1.5 ml) was stirred at 100° C. for 2 hours. After cooling to ambient temperature, water (20 ml) was added. The precipitate was collected by filtration, washed with water and dried under vacuum at 60° C. to give 6-methoxy-4-(2-methylindol-5-yloxy)-7-(3-(pyrrolidin-1-yl)propoxy)quinazoline (80 mg, 46%).
