To a solution of 2-(1-hydroxy-1-methyl-ethyl)-4-methoxy-phenol (50.57 g, 278 mmol) in 550 ml AcOH was added 10% Pd/C (as a slurry in 20 ml H2O) Ammonium formate (87.52 g, 1388 mmol) was added in portions. The mixture was warmed to 100° C. for 1 hour, cooled and filtered through a pad of celite. The celite pad was washed with ethyl acetate. The mother liquor was mixed with H2O and extracted with ethyl acetate. The combined organics were washed with H2O, washed with brine, dried over Na2SO4, filtered and concentrated in vacuo to give 2-isopropyl-4-methoxy-phenol (44.74 g, 97%) as a pale yellow oil.
