Reaction Steps
A solution of 2.3 g (6.0 mmol) of 8-chloro-6-(2-fluorophenyl)-2H,4H-pyrrolo[3,4-d][2]benzazepine-2-acetic acid methyl ester in 25 ml of tetrahydrofuran was added dropwise to a solution of 0.5 g (13 mmol) of lithium aluminum hydride in 30 ml of tetrahydrofuran which was cooled to -78°. The reaction was allowed to warm to 0° and was stirred for 2 hr. The excess lithium aluminum hydride was discharged by the addition of 0.6 ml of water, 0.6 ml of 10% sodium hydroxide and 2.0 ml of water. The resulting precipitate was removed by filtration and the filtrate was concentrated at reduced pressure to dryness. The residue crystallized from ether to give a white solid. Recrystallization from a mixture of ether and petroleum ether gave colorless prisms, mp 145°-147°.
