실험 절차

3,5-bis(1-methylethyl)-4-hydroxybenzaldehyde is acetylated with acetic anhydride in refluxing 1,2-dichloroethane, in the presence of DMAP, to provide 4-acetoxy-3,5-Bis(1-methylethyl)benzaldehyde. This material is converted by the method of example 2 into the title compound, obtained as a white solid, mp 95°-97° after recrystallization from hexane.
