Reaction Steps

To a stirred suspension of (S)-2,2-dimethyl-4-[(E)-2-(4-nitro-phenyl)-vinyl]-oxazolidine-3-carboxylic acid tert-butyl ester (2.08 g) in methanol (140 ml) were added ammonium formate (5.66 g) and palladium on charcoal (0.51 g, 10 wt %) and the mixture was heated at 60° C. for 90 min. The mixture was then cooled to room temperature, filtered through celite and the filtrate was concentrated in vacuo. The residue was purified by column chromatography (SiO2; gradient: heptane/EtOAc) to give (S)-4-[2-(4-amino-phenyl)-ethyl]-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (1.58 g, 82%) as a yellow oil. MS (ISP): 321.4 ([M+H]+).
