Procedure

A solution of 0.7 g of 2-methylthiophenol in 11.3 g of BF3 :2CH3COOH complex is heated to 70° C. and kept at this temperature for 3 hours. After returning to the ambient temperature, 11 ml of diethyl ether are added and vigorous stirring is applied for approximately 5 minutes before the excess ether is distilled off at atmospheric pressure. The acetic acid and boron trifluoride etherate which are formed are then trapped at approximately 30° C. at 67 Pa.
