Reaction Steps

To the solution of 4-[N-[1-[N-(benzofuran-2-ylcarbonyl)amino]cyclohexanecarbonyl]amino]-1-(2-cyanophenyl)piperidin-3-ol (700 mg, 1.43 mmol) obtained in Step 1 in 20 ml of dimethylformamide, were added ammonium chloride (769 mg) and sodium azide (934 mg). The reaction mixture was stirred for about 12 hours at 120° C. 20 ml of water was added to the reaction mixture, which was then acidified with a concentrated hydrochloride solution. The resulting solid was filtered and dissolved in dichloromethane. The resulting residue was purified with column chromatography to give 120 mg of the titled compound.
