実験手順

The same procedure as in Example 1 was repeated except that (+)-norephedrine hydrochloride was replaced by (-)-norephedrine hydrochloride, triglyme was replaced by 0.4 ml of dimethylformamide, dimethyl sulfide was replaced by diethyl sulfide, monochlorobenzene was replaced by 1,2-dichloroethane, (E)-1-(2,4-dichlorophenyl)-2-(1,2,4-triazol-1-yl)-4,4-dimethyl-1-penten-3-one was replaced by 0.27 g (1.85 mmoles) of phenyl isopropyl ketone, and the reduction reaction was conducted for 18.5 hours, to obtain 0.27 g of crude (-)-phenylisobutyl alcohol.
