Procedure

A solution of (2-{3-chloro-5-[(2-cyano-ethyl)-(2-fluoro-phenyl)-carbamoyl]-phenoxy}-ethyl)-pyridin-4-yl-carbamic acid tert-butyl ester (0.055 g) and water (0.020 ml) in a mixture of trifluoroacetic acid (1 ml) and dichloromethane (1 ml) was stirred at room temperature for 2 h and then the solvent removed under reduced pressure. The residue was purified by preparative hplc to give the title compound (0.035 g) as a colourless gum by concentration of the required fraction under reduced pressure and drying by repetitive addition of acetonitrile and concentration under reduced pressure.
