Reaction Steps

To the solution of 4-[N-[1-[N-(benzofuran-2-ylcarbonyl)amino]cyclohexanecarbonyl]amino]-1-[2-(1H-tetrazol-5-yl)phenyl]piperidin-3-ol (120 mg, 0.22 mmol) obtained in Step 2 in 5 ml of dimethyl sulfoxide (DMSO), was added 0.093 ml of triethylamine (0.66 mmol). The reaction mixture was cooled to 0° C. Pyridine-SO3 complex (103 mg, 0.66 mmol) was added to the reaction mixture, which was then stirred for about 2 hours at room temperature. The reaction mixture was diluted with 100 ml of ethyl acetate, washed with brine. The resulting organic layer was dried on sodium sulfate. The resulting residue was purified with column chromatography to give 50 mg of the titled compound.
