After cooling, 80 ml of water was portionwise added to the mixture, which was mixed with 90 ml of ethyl ether. The mixture was strongly acidified with conc. hydrochloric acid. The aqueous layer was separated and shaken with ethyl ether. The organic layers were combined, washed with aqueous sodium hydroxide and then saturated saline, dried over anhydrous magnesium sulfate, and the solvent was evaporated in vacuo to give 1.37 g of 2, 6-diisopropylbenzyl alcohol as white solid.
