Participants

Reaction Steps

A mixture of 2-(p-chlorophenyl)-4-[(p-chlorophenyl)thio]-5-(trifluoromethyl)pyrrole-3-carbonitrile (1.7 g, 4.1 mmol), potassium tert-butoxide (0.5 g, 4.5 mmol) and sodium iodide (0.67 g, 4.5 mmol) in tetrahydrofuran is stirred at room temperature for 15 minutes, treated with chloromethyl ethyl ether (0.425 g, 4.5 mmol), stirred at room temperature for 6 hours and poured into water. The aqueous mixture is extracted with diethyl ether. The organic extract is washed sequentially with a 2 molar potassium hydroxide solution and water, dried over anhydrous sodium sulfate and concentrated in vacuo to obtain an oil. A mixture of the oil in hexanes is stored overnight at room temperature and filtered to obtain the title product as a white solid (1.25 g, mp 98°-100° C.).
