Procedure
A solution of (2-{3-chloro-5-[[2-(2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-ethyl]-(4-fluoro-phenyl)-carbamoyl]-phenoxy}-ethyl)-pyridin-4-yl-carbamic acid tert-butyl ester (0.042 g) in mixture of trifluoroacetic acid (1 ml) and dichloromethane (1 ml) was stored at room temperature for 3 h and then the solvent removed under reduced pressure. The residue was dissolved in a mixture of acetonitrile (2 ml) amd 2M aqueous hydrochloric acid (0.5 ml) and subjected to preparative hplc to give title compound (0.022 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.
