Versuchsvorschrift

As described for in Reference Example 12, a mixture of 3.3 g of 10,11-dihydro-11-oxodibenz[b,f] [1,4]thiazepine, 25 ml of tetrahydrofuran, 4.0 ml of 10 molar borane-dimethylsulfide (2.67 equiyalents) in tetrahydrofuran is stirred at room temperature 18 hours to give, after work-up, 10,11-dihydrodibenz[b,f][1,4] thiazepine as white crystals, m.p. 145°-148° C. The preceding compound (3.5 g) is suspended in 25 ml of dichloromethane and a solution of 1.8 g of 4-[(2-methylbenzoyl) amino]benzoyl chloride in 50 ml of di-chloromethane added. To the stirred mixture is added 4 ml of triethylamine and 0.2 g of 4-(dimethylamino) pyridine. The mixture is stirred at room temperature for 20 hours. The mixture is filtered and the filtrate concentrated. The residue is purified by chromatography on silica gel with hexane-chloroform-ethyl acetate (2:1:1) as solyent to give 2.2 g of yel]ow crystals. A sample (0.80 g) is further purified by thick layer chromatography on silica gel with hexane-chloroform-ethyl acetate (2:1:1) as solvent to give 0.50 g of crystals, 76°-78° C.
