2-Propenal, 3-[4-(1,1-dimethylethyl)phenyl]-2-methyl- → 3-(4-tert-Butylphenyl)-2-methylprop-2-en-1-ol

Participants

Reaction Steps

404.5 g of 3-(p-tert.butyl-phenyl)-2-methyl-acrolein are dissolved in 2500 ml of methanol and treated portionwise with 38 g of sodium borohydride while cooling with ice. Subsequently, the mixture is stirred at room temperature for 2.5 hours, poured into 2500 ml of ice-cold 2-N hydrochloric acid and exhaustively extracted with hexane. The combined hexane extracts are washed neutral with water, dried over sodium sulphate and evaporated. Vacuum distillation yields pure 3-(p-tert.butyl-phenyl)-2-methyl-allyl alcohol of boiling point 119° C./0.005 Torr.
