1-(4-Pentafluoroethylbenzyl)-3-(2,2,2-trifluoroethyl)thiourea → 2-(2,2,2-Trifluoroethylimino)-3-(4-pentafluoroethylbenzyl)-5-(4-methylphenyl)-tetrahydro-1,3,5-thiadiazin-4-one

Participants

Reaction Steps

0.71 g of N-chloromethyl-N-(4-methylphenyl)carbamoyl chloride and 1.20 g of 1-(4-pentafluoroethylbenzyl)-3-(2,2,2-trifluoroethyl)thiourea were dissolved in 30 ml of toluene, and the solution was heated under reflux for 4 hours. After the reaction, toluene was evaporated under reduced pressure. The resulting oily product was purified by column chromatography silica gel; developing solvent hexane/ethyl acetate (10:1)]to give 0.72 g of the captioned compound.
