실험 절차

To a solution of lithium aluminum hydride in tetrahydrofuran (1M, 12.2 ml) and dry tetrahydrofuran (30 ml) was added aluminum chloride (1.62 g) in portions, with stirring. After five mins, 1-benzyl-3-methyl-1,3,9,10,11,12-hexahydro-2H-quino[4,3,2-ef][1,4]benzoxazepin-2-one (4.38 g) was added and stirring was continued overnight. Ethyl acetate (200 ml) and 10% sodium hydroxide solution (200 ml) were added, and the organic layer was separated, dried over anhydrous sodium magnesium sulfate, and concentrated. Recrystallization of the residue from methanol/diethyl ether gave 2.82 g (67%) of product, mp 151.5°-153° C.
