Reaction Steps

A solution of 2,4,5-tribromopyrrole-3-carbonitrile (3.0 g, 0,091 mo1) in tetrahydrofuran is treated portionwise with potassiumt-butoxide (1,33 g, 0.012 mol) at room temperature, stirred for 20 minutes, treated dropwise with a solution of methyl chloroformate (1,29 g, 0.014 mol) in tetrahydrofuran, stirred for 2 1/2 days, poured into water and extracted with ether. The combined ether extracts are washed with brine, dried over MgSO4 and concentrated in vacuo to give a brown solid residue. The residue is recrystallized from ethyl acetate/hexanes to afford the title compound as a tan solid, 1.4 g (39.5%) mp 119.5° to 122.0° C.
