Reaction Steps

To a solution of (S)-4-{2-[4-(4-chloro-phenylamino)-phenyl]-ethyl}-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (220 mg) in THF (3 ml) in a pressure tube was added HCl solution (2.55 ml, 4 M solution in dioxane). The tube was sealed and the reaction mixture was shaken at 60° C. for 2 hours. The mixture was then cooled to room temperature and poured into 1 M aq. NaOH and extracted with EtOAc. The phases were then separated and the organic phase was dried over sodium sulphate and concentrated in vacuo to afford (S)-2-amino-4-[4-(4-chloro-phenylamino)-phenyl]-butan-1-ol (148 mg, quant.) as a yellow oil which was used in the next step without further purification. MS (ISP): 293.0 ([{37Cl}M+H]+), 291.1 ([{35Cl}M+H]+).
