Participants

Reaction Steps

2.33 g of 2.4-dichloro-3-methylphenol was dissolved in 15 ml of tetrahydrofuran, and 1.84 ml of triethylamine was added while stirring the solution. Then, 2.0 g of 3-chlorosulfonyl-1,2,4-triazole was gradually added while cooling with ice and stirring the solution. Then, the solution was stirred at room temperature for 14 hours. Tetrahydrofuran was removed by distillation at reduced pressure, 2N hydrochloric acid was added, and extracted with ethyl acetate. The organic layer was washed with brine, and dried with magnesium sulfate. Then, the solvent was removed by distillation, so that coarse crystals were obtained. The coarse crystals were recrystallized from n-hexane/ethyl acetate, so that 2.25 g of the titled compound was obtained.
