Reaction Steps
Concentrated aqueous ammonia (5 ml) was added to a solution of 4-(5-acetoxy-4-chloro-2-fluoroanilino)-6-methoxy-7-(2-methoxyethoxy)quinazoline (180 mg, 0.4 mmol) in methanol (50 ml). The mixture was stirred at ambient temperature for 3 hours, and then diluted with water. Most of the methanol was removed by evaporation and the resulting precipitate collected by filtration, washed with water and dried to give 4-(4-chloro-2-fluoro-5-hydroxyanilino)-6-methoxy-7-(2-methoxyethoxy)quinazoline (73 mg, 45%).
