Procedure

A mixture of (2R,3R,4R)-3,4-dibenzyloxy-2-benzyloxymethyl-1-methylpyrrolidine (Compound 3) (38 mg, 0.067 mmol), 10% Pd/C (30 mg), 4 N HCl (0.1ml) and 99.9% ethanol (5 ml) was reduced in a Parr apparatus at 40 psi for 20 hours. The mixture was filtered and evaporated in vacuo to give (2R,3R,4R)-3,4-dihydroxy-2-hydroxymethyl-1-methylpyrrolidine, hydrochloride (15 mg, yield 88%) as a yellow oil.
