10% Pd—C (0.1 g) was added to a solution of 4-{1-ethyl-1-[4-(3-hydroxy-4,4-dimethyl-1-pentynyl)-3-methyl-phenyl]-propyl}-2-methyl-phenol (Example 3-(2), Enantiomer B; 725 mg, 1.92 mmol) in ethyl acetate (10 mL), and the mixture was stirred in a hydrogen atmosphere for 40 minutes. The reaction mixture was filtered and then concentrated under reduced pressure to give the title compound (720 mg, 98%).
