実験手順
To a first reaction vessel containing tetrahydrofuran (2.4 mL) at 0° C. was added aluminum chloride (167 mg, 1.26 mmol). To the resulting suspension was slowly added lithium aluminum hydride (3.77 mmol). To a second reaction vessel containing THF (4 mL) was added trans-8-chloro-10,11-dihydro-11-[(methylamino)methyl]-dibenz[b,f]oxepin-10-carboxylic acid hydrochloride (I).HCl (0.4 g, 1.26 mmol). At −10° C., the contents of the first reaction vessel were added to the second reaction vessel. After 30 minutes the reaction mixture was quenched with water and extracted with toluene. The toluene was dried with magnesium sulfate and evaporated. This provided crude trans-5-chloro-2,3,3a,12b-tetrahydro-2-methyl-1H-dibenz[2,3:6,7]-oxepino[4,5-c]pyrrole (A) in nearly quantitative yield with a purity of 63%; 1H-NMR (400.13 MHz in CDCl3 relative to TMS) δ 2.54 (s, 3H), 3.15 (m, 2H), 3.25 and 3.61 (2×m, 4H), 7.01-7.36 (m, 7H).
