Reaction Steps

A suspension of 4-chloro-2-fluoro-5-hydroxyphenylamino-7-[2-acetoxy-3-(pyrrolidin-1-yl)propoxy]-6-methoxyquinazoline (170 mg) in methanol saturated with ammonia (6 ml) was stirred at ambient temperature for 2 hours. The volatiles were removed under vacuum. The residue was partitioned between ethyl acetate and water. The pH of the aqueous layer was adjusted to 6.5. The organic layer was separated, washed with water, dried (MgSO4) and evaporated. The residue was triturated under diethyl ether, filtered, washed with ether and dried under vacuum to give 4-chloro-2-fluoro-5-hydroxyphenylamino-7-[2-hydroxy-3-(pyrrolidin-1-yl)propoxy]-6-methoxyquinazoline (20 mg).
