A solution of {2-[3-(allyl-cyclohexyl-carbamoyl)-5-chloro-phenoxy]-ethyl}-pyridin-4-yl-carbamic acid tert-butyl ester (0.032 g) in a mixture of dichloromethane (1 ml) and trifluoroacetic acid (1 ml) was stored at room temperature for 2 h and then concentrated under reduced pressure. The residue was subjected to preparative hplc and the title compound (0.027 g) was obtained 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.
