HCID 21456046HCID 21456046, compound

Procedure

100 g of 2-(phenylthio)-5-trifluoromethyl-benzoic acid, 750 ml of absolute methanol and 100 ml of sulphuric acid are heated under reflux for 24 hours. The solution is concentrated under reduced pressure and treated with water and benzene. After equilibration, the organic phase is washed successively with saturated aqueous sodium chloride solution, saturated aqueous sodium bicarbonate solution and saturated aqueous sodium chloride solution. The benzene phase is subsequently dried over sodium sulphate, filtered and evaporated. There is obtained methyl 2-(phenylthio)-5-trifluoromethyl-benzoate as a yellow oil.
