Procedure

A solution of 4.0 g (9.76 mmol) of 9-chloro-7-(2-fluorophenyl)-5H-pyrimido[5,4-d][2]benzazepine-2-acetic acid ethyl ester in 30 ml of ethanol and 25 ml of 1N sodium hydroxide was heated on the steam bath for 3 hr. The mixture was partitioned between 75 ml of water and 75 ml of ether. The basic layer was acidified with acetic acid and extracted with dichloromethane (2×100 ml), which was dried and evaporated. The resulting oil was crystallized from methanol and recrystallized from dichloromethane/ether/petroleum ether to give off-white prisms, mp 138°-140° C.
