152 mg of p-toluenesulfonyl chloride was added to a mixture of 246 mg of [2-(2-ethylsulfanylphenyl)-7-trifluoromethylpyrido[3,2-d]pyrimidin-4-yl]-hydrazine, 74 mg of pyridine and 5 ml of acetonitrile, under ice cooling, and the mixture was stirred at room temperature for 15 minutes. A saturated aqueous sodium bicarbonate solution was added to the reaction mixture, and the mixture was extracted with t-butyl methyl ether. The organic layer was washed with water and dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The resulting residue was washed with t-butyl methyl ether and n-hexane, and then dried to obtain 156 mg of 1-[2-(2-ethylsulfanylphenyl)-7-trifluoromethylpyrido[3,2-d]pyrimidin-4-yl]-2-tosylhydrazine.
