Methyl 3-{(1S)-2-methoxy-(1-methylethyl)oxy}-5-{[(2-methylphenyl)methyl]oxy}benzoate (50 g, 0.152 mol) was dissolved in THF/ethanol (1:1, 600 ml) and 10% Palladium on carbon (5.0 g) was added. The mixture was hydrogenated under normal pressure at room temperature. The catalyst was filtered off, and the filtrate concentrated in vacuo to give the desired compound (36.7 g, 99%).
