Reaction Steps

A mixture of N′-acetyl-2-[(trans-4-{6-[(2′-cyanobiphenyl-4-yl)methyl]-5-oxo-7-propyl[1,2,4]triazolo[1,5-a]pyrimidin-4(5H)-yl}cyclohexyl)oxy]acetohydrazide (0.42 g), 4-methylbenzenesulfonyl chloride (0.16 g) and pyridine (5 mL) was stirred at 110° C. for 16 hr. 4-Methylbenzenesulfonyl chloride (0.083 g) was added, and the mixture was stirred at 110° C. for 8 hr. Ethyl acetate and 1 M hydrochloric acid were added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.24 g, 60%).
