実験手順

Hydrogen bromide gas is bubbled through a mixture of (3,4-dichlorophenacyl)malononitrile (10.0 g, 0.0395 mol) in ether (150 mL) and chloroform (100 mL) at a moderate rate, keeping the reaction mixture temperature below 35°-40° C. After ten minutes, TLC shows the reaction is complete by UV analysis. The reaction mixture is poured into an ice-water mixture, the layers are separated and the aqueous layer is extracted with ether. The combined organic layer and ether extracts are dried and concentrated in vacuo to give a brown solid. The brown solid is washed with methylene chloride and filtered to obtain the title compound as an off-white solid (3.0 g, 24%, mp >200° C.) which is identified by IR and NMR spectral analyses.
