Procedure

A mixture of 1-benzyl-3-(tert-butyl-dimethyl-silanyloxymethyl)-pyrrolidine-3-carboxylic acid ethyl ester (690 mg, 1.83 mmol), ammonium formate (461 mg, 7.31 mmol), 10% Pd/C (100 mg) in methanol (10 ml) and water (1 ml) was refluxed overnight. The mixture was filtered through celite, washed with ethyl acetate. The combined filtrate was concentrated and the residue was taken into ethyl acetate, washed with brine and dried over MgSO4. Evaporation of solvent provided the title compound as oil (444 mg, 84%).
