Procedure
A 3.8 g. portion of 3-(3-trifluoromethylphenylaminomethyl)pyridine was dissolved in 15 ml. of dichloromethane and to it was added 2.7 g. of potassium carbonate and 1.6 ml. of methanesulfonyl chloride. The mixture was stirred at ambient temperature overnight, and at a gentle reflux for another day. Another 1.6 ml. of methanesulfonyl chloride was added, and the mixture was stirred under reflux for 3 days more. It was then cooled, and diluted with 20 ml. of aqueous sodium bicarbonate. The organic phase was separated, washed with water, dried and evaporated under vacuum. The residue was triturated with diethyl ether and petroleum ether, and dried to give 4.7 g. of the desired product, m.p. 106°-110°.
