反応手順
To a solution of 5-benzyloxy-α,α,α′,α′-tetramethyl-1,3-benzenedimethanol (22.9 g, 76 mmol) in ethanol (500 mL), concentrated hydrochloric acid (2.6 mL) and a 10% palladium-carbon catalyst (8.0 g) were added. Under hydrogen atmosphere, the mixture was stirred for 23 hours at 60° C. The reaction mixture was subjected to filtration, and the filtrate was concentrated under reduced pressure, to thereby yield 13.6 g of 3,5-diisopropylphenol as a solid (yield 100%). The solid was crystallized from hexane, to thereby yield colorless needles.
