Abstract
PURPOSE: To prepare the titled compound useful as a synthetic intermediate of pharmaceuticals or pesticides, easily, in high yield, by reacting benzotrifluoride with fuming sulfuric acid, and treating the product with sulfur chloride or a polychlorinated hydrocarbon.
CONSTITUTION: Benzotrifluoride is made to react with fuming sulfuric acid of 10W90% concentration in the presence of a solvent such as carbon tetrachloride, and the reaction product is treated with sulfur chloride or a polychlorinated hydrocarbon (e.g. carbon tetrachloride) to obtain the objective compound of formula. When carbon tetrachloride is used as the solvent, the mixture obtained by the reaction of the raw material with the fuming sulfuric acid can be converted to the objective compound by heating and refluxing the mixture without separation.
EFFECT: The treatment can be carried out in a single reactor.
