5H-Dibenzo[a,d]cyclohepten-5-one (10 g) is dissolved in 80 ml of isopropyl alcohol and sodium borohydride (1.8 g) is added at once. The mixture is stirred at room temperature for two hr. 5 ml of water are added to quench the reaction and the solvent is evaporated. The residue is taken up in diethyl ether and washed with water, dried over MgSO4 and evaporated. (9.8 g 98% yield) of 5H-dibenzo-[a,d]-cyclohepten-5-ol is obtained.
