Participants

Reaction Steps

5.15 ml (5.55 g) of thiophenol and 7.0 ml of triethylamine are added successively while stirring to a solution of 10.93 g of 2-n-butylthio-4-chloro-5-cyanothiazole prepared according to Example V(b), in 100 ml of acetonitrile. After stirring at room temperature for another hour and leaving to stand overnight, the reaction mixture is evaporated. The residue is dissolved in methylene chloride, after which the organic solution is successively washed with water, 1N sodium hydroxide solution and water, and is then dried, filtered and evaporated. Chromatography in petroleum ether (40-60)/diethyl ether 3:1 v/v as a solvent over a 1400 ml dry silica gel column provides the desired product in a yield of 7.24 g; oil; Rf (petr.ether/diethyl ether 3:1 v/v) 0.35; identification by means of I.R. spectrum.
