Participants

Reaction Steps

The starting material is prepared as follows: To the stirred suspension of 1.09 g of 7-chloro-5-hydroxy-2,3-dihydro-1-benzothiepin-1,1-dioxide in 20 ml of benzene the solution of 0.5 g of titanium tetrachloride in 10 ml of benzene is added dropwise while cooling with ice, and the mixture stirred for 1/2 hour at 0°. Thereupon the solution of 0.7 g of dimethylamine in 10 ml f benzene is added dropwise and the mixture allowed to warm up to room temperature. It is filtered, the filtrate evaporated, and the residue recrystallized from diethyl ether, to yield the 7-chloro-5-dimethylamino-2,3-dihydro-1-benzothiepin-1,1-dioxide melting at 93°-95°.
