Reaction Steps

A solution of 4-(2-nitro-phenyl)-4-trimethlysilanyloxy-butyric acid ethyl ester (200 mg, 0.6 mmol) in dry EtOAc (5 mL) was hydrogenated (1 atm) in the presence of Pd/C (20 mg) overnight Then the mixture was filtered and evaporated. The residue was dissolve in dry MeOH (5 mL) and was further hydrogenated (1 atm) in the presence of Pd/C (20 mg) for 1 h. The mixture was then filtered and the filtrate evaporated. Purification of this residue by filtration over silica gel, eluting with hexane: ethyl acetate (8:1) afforded the title compound (130 mg, 72%) as a colorless oil; m/z 295 (M).
