Procedure

A solution of methyl 3-{[(1R)-1-methyl-2-(methyloxy)ethyl]oxy}-5-[(phenylmethyl)oxy]benzoate in THF (5 mL) and ethanol (5 mL), containing 10% palladium on carbon, was stirred under an atmosphere of hydrogen for 16 hours. The palladium on carbon was removed by filtration and the filtrate evaporated under reduced pressure to give the desired material as a clear gum (723 mg).
