In a dry flask under nitrogen atomosphere was suspended 3.25 g (0.086 mol) lithium aluminum hydride and 250 ml of dry diethyl ether. The suspension was cooled in an ice/water bath, then 24.5 g (0.184 mol) of 2-methylacetophenone was added dropwise. After 12 hours the excess hydride was decomposed with 100 ml of ethyl acetate. The reaction mixture was washed with ammonium chloride solution and water. The organic layer was dried (MgSO4) and concentrated under reduced pressure to give 25.0 g of a clear oil.
