Reaction Steps

49.9 g of 2-bromo- 10,11-dihydro-dibenzo[b,f]thiepin-10-ol, 250 ml of benzene and 18 g of finely powdered calcium chloride are saturated with hydrochloric acid gas at 15° C and then stirred for a further 3 hours at room temperature. The precipitate is filtered off and washed with benzene. The filtrate is concentrated under reduced pressure. There is obtained 2-bromo-10-chloro- 10,11-dihydro-dibenzo[b,f]thiepin of melting point 122.5°-124° C.
