17.8 G. of 3-methoxy-8-methylthio-dibenzo[b,f]thiepin-10(11H)-one are suspended in 150 ml. of ethanol and treated with 3.8 g. of sodium borohydride. The mixture is stirred for 90 minutes. Then, it is treated with water and extracted with ether. The organic phase is washed with water, dried over magnesium sulfate, evaporated, and there is obtained 10,11-dihydro-3-methoxy-8-methylthio-dibenzo[b,f]thiepin-10-ol having a melting point of 122°-124° C.
