Procedure
4,5-bis-(2-Furyl)-1H-2-imidazolethiol (8.1 g; 39.4 mmoles) was reacted with 7.0 g of tetrafluoroethylene and the product purified by chromatography on Silicar CCNo. 7 with chloroform to give 3.0 g of 4,5-bis-(2-furyl)-2-(1,1,2,2-tetrafluoroethylthio)-1H-imidazole, m.p. 166°-167°: (recrystallized from 1-chlorobutane).
