Reaction Steps

To a mixture of {8-(3,4-dichlorophenyl)-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridin-8-yl}methanol (178 mg) in pyridine (3 mL) was added 4-methylbenzenesulfonyl chloride under ice-cooling, and the mixture was stirred at room temperature for 4 hr. 4-Methylbenzenesulfonyl chloride (84 mg) was further added, and the mixture was stirred at room temperature for 2 hr, and at 50° C. overnight. Water was added to the reaction mixture, and the precipitated solid was collected by filtration. The solid was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (163 mg).
