Procedure

To the solution of 4-[N-[1-[N-(benzofuran-2-ylcarbonyl)amino]cyclohexanecarbonyl]amino]-1-[2-(N,N-dimethylcarbamoyl)phenyl]piperidin-3-ol (1.8 g) obtained in Step 2 in 10 ml of dimethylsulfoxide (DMSO), was added 2 ml of triethylamine. The reaction mixture was cooled to 0° C. Pyridine-SO3 complex (1.8 g) was added slowly to the reaction mixture, which was then stirred for about 2 hours at room temperature. The reaction mixture was diluted with 50 ml of ethyl acetate, washed with brine. The resulting organic layer was dried and concentrated on sodium sulfate. The resulting residue was purified with column chromatography to give 1.2 g of the titled compound.
