Triethylamine → 4-Butyl-5-chloromethyl-2-(4-trifluoromethyl-phenyl)-thiazole

Participants

Reaction Steps

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.
