Reaction Steps
A solution of 1 g of 5-(p-hydroxy-α-methylstyryl)-1,1,3,3-tetramethyl-2-indanone in 10 ml of tetrahydrofuran is added dropwise while cooling with ice to a suspension of 100 mg of lithium aluminium hydride in 5 ml of tetrahydrofuran and the mixture is subsequently left to stir at room temperature for 2 hours. After the dropwise addition of 50 ml of 2N hydrochloric acid at 0° the mixture is extracted with ethyl acetate and the organic phase is washed with water, dried and evaporated. After filtration of the crude product over silica gel (elution agent hexane/ethyl acetate=1:1) it is recrystallized from ethyl acetate/hexane and there are obtained 500 mg of 5-(p-hydroxy-α-methylstyryl)-1,1,3,3-tetramethyl-2-indanol in colourless crystals, m.p. 148°-149°.
