Versuchsvorschrift

A solution of 5-tert-butyl-2-hydroxymethyl-phenol (Intermediate 106, 0.215 g, 1.19 mmol) in ethyl acetate was treated with 5% palladium on carbon (0.04 g) and the resulting reaction mixture was stirred under an atmosphere of hydrogen at ambient temperature for 2.5 h. The reaction mixture was then filtered over a bed of celite and the filtrate was evaporated in vacuo to afford the title compound as a white solid (0.19 g, 97%).
