Procedure
A solution of 6.9 g of 4-(4-chlorophenyl)-5-(2-thienyl)-1H-2-imidazolethiol in 40 ml of dimethylformamide and 1.5 ml of diisopropylamine was pressured in a bomb with 3 g of tetrafluoroethylene and shaken until there was no further pressure drop. The bomb contents were poured into water, the pH adjusted to 8 and the solution extracted with chloroform. The extract was dried and concentrated. It was chromatographed on silica gel (Silicar CC-4) to give 5.5 g of a cut which was dissolved in hot 1-chlorobutane. On cooling 4.5 g of product was obtained, m.p. 161.5°-163° C.
