Reaction Steps

To 100 mg of (10,11-dihydro dibenzo[b,f]thiepin-2-yl)-acetic acid in 5 ml of dry tetrahydrofuran were added 0.2 g of oxalyl chloride and a drop of dimethylformamide, and the mixture was stirred with ice cooling under a dry atmosphere for 3 hours. To the mixture was added 5 ml of tetrahydrofuran containing 1% ammonia, and the mixture was stirred under a dry atmosphere at room temperature for 14 hours. After the addition of water, the mixture was extracted with ethyl acetate. The extract was washed with a 1% sodium hydroxide solution and then with a saturated sodium chloride solution and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain a residue, which was recrystallized from ethyl acetate, thereby obtaining 66 mg (yield: 66%) of (10,11-dihydro dibenzo[b,f]thiepin-2-yl)-acetamide as colorless crystals having a melting point of 188°-189° C.
