Versuchsvorschrift

To a solution of lithium aluminum hydride in tetrahydrofuran (1M, 14.22 ml) and dry tetrahydrofuran (30 ml) was added aluminum chloride (1.90 g) in portions, with stirring. After five mins, 1-ethyl-3-methyl-1,3,9,10,11,12-hexahydro-2H-quino[4,3,2-ef][1,4]benzoxazepin-2-one (4.21 g) was added and stirring was continued for 0.5 hr. The reaction mixture was quenched with ethyl acetate (200 ml) and 10% sodium hydroxide solution (200 ml). The organic layer was separated, dried over anhydrous magnesium sulfate, filtered, and concentrated. Recrystallized of the residue from diethyl ether/pentane gave 2.17 g (54%) of product, mp 101°-103° C.
