A boiling suspension of of lithium aluminium hydride (0.8 g) in absolute dioxan (100 ml) is mixed with 7,8-dimethoxy-1,3-dihydro-2H-3-benzazepin-2-one (2.2 g, 0.01 mol) and then refluxed for 3 hours. While cooling with ice water, 10% ammonium chloride solution is added and the precipitate formed is suction filtered. The fitrate is evaporated in vacuo to a volume of about 20 ml, the white precipitate obtained is suction filtered and washed with a little dioxan.
