Procedure

17 G. of 3-bromo-10,11-dihydro-11-oxodibenzo[b,f]thiepin (0.056 mole) are dissolved in a mixture of 150 cc. DMF and 150 cc absolute alcohol. 1.7 G. sodium borohydride (0.045 mole) are added and the mixture is left stirring overnight at room temperature. The ethanol is evaporated and the residual DMF solution is diluted with water and extracted with ether three times. The ether extracts are washed several times with water, dried and evaporated to a thick oil. A quantitative yield of the alcohol is obtained.
