Reaction Steps
A suspension of (1S,3S,4S)-3-[(benzyloxy)methyl]-4-{[tert-butyl(dimethyl)silyl]-oxy}cyclopentyl methanesulfonate (690 mg, 0.0017 mol) and Palladium hydroxide, 20 wt. % Pd on carbon (160 mg, 0.00012 mol) in methanol (10 mL, 0.2 mol) was stirred under an atmosphere of hydrogen for 2 hours. The reaction was purged with nitrogen and filtered the mixture through celite with DCM. The filtrate was concentrated to obtain 350 mg (65%).
