Yield:4568-71-2 44%

Reaction Conditions:

in acetonitrile for 6.5 h;Reflux;

Steps:

7 Synthesis of 3-(1,1,1-trifluorobutyl)-5-(2-hydroxyethyl)-4-methylthiazolium bis(trifluoromethanesulfonyl)imide
2.86 kg of methylhydroxyethylthiazole, 8.58 kg of acetonitrile and 2.54 kg of benzyl chloride were charged in a 20 L reactor equipped with a stirrer and refluxed for 6.5 hours. After cooling the reaction solution to room temperature to give a solid, 3 kg of acetonitrile was added to the reaction solution and filtration was carried out. The obtained solid was washed with 2.0 kg of acetonitrile and dried under reduced pressure to obtain 2.36 kg of 3-benzyl-5- (2-hydroxyethyl) -4-methylthiazolium chloride (yield: 44% ).
