Versuchsvorschrift

To a mixture of 3.3 g of 10,11-dihydro-11-oxodibenz[b,f][1,4]thiazepine in 25 ml of tetrahydrofuran is added 4.0 ml of 10 molar borane-dimethylsulfide in tetrahydrofuran. The mixture is stirred at room temperature for 18 hours, 50 ml of anhydrous methanol added and the solvent removed. An additional 30 ml of methanol is added and the solvent removed to give white crystals. A sample is purified by chromatography on silica gel with hexane-chloroform-ethyl acetate (2:1:1) as solvent to give white crystals, m.p. 145°-148° C.
