Procedure

To the solution of 4-[N-[1-[N-(benzofuran-2-ylcarbonyl)amino]cyclohexanecarbonyl]amino]-1-(4-fluoro-2-methoxyacetylaminophenyl)piperidin-3-ol (1.1 g) obtained in Step 3 in 5 ml of dimethyl sulfoxide, was added dropwise 1.2 ml of triethylamine. The reaction mixture was cooled to 0° C. Pyridine-SO3 complex (0.9 g) was added to the reaction mixture, which was then stirred for about 4 hours at room temperature. The reaction mixture was diluted with 20 ml of ethyl acetate and washed with brine. The resulting organic layer was dried and concentrated on sodium sulfate. The resulting residue was purified with column chromatography to give 820 mg of the titled compound.
