Versuchsvorschrift

To the solution of 4-[N-[1-[N-(benzofuran-2-ylcarbonyl)amino]cyclohexanecarbonyl]amino]-1-(4-fluoro-2-trifluoromethylphenyl)piperidin-3-ol (0.15 g) obtained in Step 1 in 3 ml of dimethyl sulfoxide (DMSO), was added 0.16 ml of triethylamine. The reaction mixture was cooled to 0° C. Pyridine-SO3 complex (0.15 g) was added slowly to the reaction mixture, which was then stirred for about 4 hours at room temperature, diluted with 20 ml of ethyl acetate, washed with brine, and dried and concentrated. The resulting residue was purified with column chromatography to give 84 mg of the titled compound as white solid.
