42 g of p-[(1,5-dimethylhexyl)oxy]benzoic acid methyl ester is dissolved in 250 ml of benzene and, with stirring, treated dropwise with 50 g of 70% bis(2-methoxy-ethoxy)sodium aluminum hydride. The reaction solution is further stirred at 25°C. for 5 hours and thereafter treated with water. The organic phase is separated off, dried under sodium sulfate, carefully filtered (using a filter aid) and evaporated under reduced pressure. There is obtained a residual of p-[(1,5-dimethylhexyl)oxy]benzyl alcohol; B.P. 180°-182°C/1.0 mmHg.
