Reaction Steps
To a mixture of potassium tert-butoxide (0.62 g, 0.0055 mol) and tetrahydrofuran (50 mL) is added 2,4-dichloro-5-(3,4-dichlorophenyl)pyrrole-3-carbonitrile (1.3 g, 0.0043 mol) followed by chloromethyl ethyl ether (0.52 g, 0.0055 mol). After stirring the reaction mixture overnight, TLC (1:1 hexane/ethyl acetate shows no remaining starting pyrrole and the reaction is concentrated in vacuo. Addition of water to the residue affords a solid which is collected and dried to give the title compound as a brown solid (1.4 g, 90%, mp 106°-109° C.) which is indentified by IR and NMR spectral analyses.
