A boiling suspension of 0.8 gm of lithium aluminium hydride in 100 ml of absolute dioxane was mixed with 2.2 gm (0.01 mol) of 7,8-dimethoxy-1,3-dihydro-2H-3-benzazepin-2-one, and the mixture was refluxed for 3 hours. Ammonium chloride solution (10%) was added while cooling with ice water, and the precipitate formed thereby was suction-filtered off. The filtrate was evaporated in vacuo to a volume of about 20 ml, and the resulting white precipitate was suction-filtered off and washed with a little dioxane.
