실험 절차

To a solution of 1.6 g. 2-(p-biphenylyl)-2-penten-4-one in 25 ml. of dry tetrahydrofuran, at 0° C., 10 ml. of a solution of 25% (W/W) of sodium aluminum diethyl dihydride in toluene is dropwise added. After 20 minutes at 0° C., the mixture is poured onto ice and extracted with chloroform. Evaporation of the chloroform gives 2-(p-biphenylyl)-2-penten-4-ol, m.p. 137°-138° C.
