Participants

Reaction Steps

Into the mixture of 20 ml of toluene and 10 ml of water were added 2.53 g of 4-methoxybenzylisothiourea hydrogen chloride, 2.03 g of perchloromethyl mercaptan, and 50 mg of benzyltriethylammonium chloride, and a solution of 1.74 g of sodium hydroxide in 10 ml of water was added dropwise to the mixture at about 0° C. over 4 hours. After the addition, the mixture was stirred for 1 hour at room temperature. Into the reaction mixture was added t-butyl methyl ether, and extracted. The organic layer was dried over anhydrous sodium sulfate, concentrated, and the residue obtained was subjected to silica gel column chromatography to give 5.38 g of 5-chloro-3-(4-methoxybenzyl)thio-1,2,4-thiadiazole.
