Procedure

A mixture of 3.00 g (8.37 mmol) of 5-methyl-N-(2,6-dichlorophenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide and 1.16 g (8.37 mmol) of anhydrous powdered K2CO3 in 100 ml of acetone was heated at reflux for 30 minutes. A solution of 1.18 g (8.37 mmol) of benzoyl chloride in 10 ml of acetone was added, and the reaction was heated at reflux for 115 min. The reaction was filtered, and the filtrate was evaporated at reduced pressure. The solid residue was collected by filtration, washed thoroughly with aqueous NaHCO3 and H2O and dried to yield 2.75 g (72%) of the desired product as a solid, mp 187°-189° C. IR and 1H NMR spectra were in agreement with the assigned structure.
