Triethylamine → 5-Chloromethyl-4-methyl-2-(4-trifluoromethyl-phenyl)-thiazole

Participants

Reaction Steps

3.0 g of [4-Methyl-2-(4-trifluoromethyl-phenyl)-thiazole-5-yl]-methanol were dissolved in 50 ml dichloromethane, 3.0 ml of triethylamine were added followed by the addition of 1.36 ml of methanesulfonylchloride. The reaction mixture was stirred at room temperature for two hours. 100 ml dichloromethane were added and the mixture washed with saturated sodium hydrogen carbonate solution, water and brine. The organic layer was dried over MgSO4. The solvent was removed in vacuo to obtain 3.3 g of crude 5-Chloromethyl-4-methyl-2-(4-trifluoromethyl-phenyl)-thiazole as a brown oil.
