Procedure
1.0 g [4-Butyl-2-(4-trifluoromethyl-phenyl)-thiazole-5-yl]-methanol were dissolved in 50 ml dichloromethane, 0.88 ml triethylamine and 0.39 ml methanesulfonyl chloride were added. The reaction mixture was stirred at room temperature for a period of three hours then 100 ml of dichloromethane were added and the reaction mixture washed with 50 ml of saturated NaHCO3 solution , water and brine. The organic layer was dried over MgSO4 and the solvent removed under reduced pressure. This provided 1.0 g 4-Butyl-5-chloromethyl-2-(4-trifluoromethyl-phenyl)-thiazole as yellow oil.
