Reaction Steps

A solution of 2,5-dibromo-4-(trifluoromethyl)pyrrole-3-carbonitrile (0.10 g, 0.30 mmol) in tetrahydrofuran is treated with solid potassium t-butoxide (0.053 g, 0.49 mmol), stirred for 1 hour at 25° C., treated dropwise with methyl iodide (0.067 g, 0.47 mmol), stirred for 2 hours at 25° C. and for 1 hour at 50° C. and diluted with water and ether. The phases are separated and the organic phase is washed sequentially with water and brine, dried over MgSO4 and concentrated in vacuo to afford the title compound as a white solid, 0.09 g, mp 101°-104° C.
