Participants

Reaction Steps

A solution of 3-bromo-5-(p-chlorophenyl)-2-(trifluoromethyl)-4-[(trifluoromethyl)thio]pyrrole (0.6 g, 1.4 mmol) and potassium tert-butoxide (0.19 g, 1.7 mmol) in tetrahydrofuran is stirred for 15 minutes, treated with chloromethyl ethyl ether (0.16 g, 1.7 mmol), stirred for 30 minutes and diluted with an ether/water mixture. The organic phase is separated, dried over anhydrous magnesium sulfate and concentrated in vacuo to obtain a residue. Chromatography of the residue using silica gel and a 1:9 ethyl acetate/hexanes solution gives the title product as an amber oil which is identified by 1HNMR and 13CNMR spectral analyses.
