Procedure

10 g of 10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-one are dissolved in 100 ml of dioxane and treated with 3.2 g of sodium borohydride in 5 ml of water. The mixture is subsequently stirred for 20 hours at room temperature. Then the mixture is concentrated under reduced pressure and the residue partitioned between ether and water. The ethereal solution is washed with saturated sodium chloride solution, dried over sodium sulphate and evaporated. There is obtained 10,11-dihydro-2-methyl-dibenzo[b,f]thiepin-10-ol as a colourless oil.
