実験手順
Methyl 3-cyanocinnamate (42 pw) is added to a mixture of trichloroacetonitrile (194.4 pw) and aluminum bromide (7.2 pw) in the absence of moisture and at about 25° C. Hydrogen chloride is then introduced over a period of 3 hours with stirring, while keeping the temperature constant. Stirring is discontinued, and the mixture is allowed to react further overnight. In this step, too, a constant temperature of 25° C. is maintained. The solidified mixture is dissolved in 800 pw of dichloromethane, washed with water, and the organic phase is dried over sodium sulfate. Evaporation of the solvent gives a white residue, which is recrystallized from methanol or benzene.
