Procedure

41 μl of hydrazine monohydrate was added to a mixture of 263 mg of 4-chloro-2-(2-ethylsulfanylphenyl)-7-trifluoromethylpyrido[3,2-d]pyrimidine and 4 ml of THF, 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 then concentrated under reduced pressure to obtain 246 m of [2-(2-ethylsulfanylphenyl)-7-trifluoromethylpyrido[3,2-d]pyrimidin-4-yl]-hydrazine.
