1,2-Dibromoethane → 1-(2-Methoxyphenyl)cyclopropane-1-carbonitrile

Participants

Reaction Steps

A mixture of (2-methoxyphenyl)acetonitrile (147 g and 1,2-dibromomethane (168 ml) in dimethylsulphoxide (250 ml) was added over 1 hour to a stirred suspension of powdered potassium hydroxide (250 g) and 18-Crown-6 (5 g) in dimethylsulphoxide (1200 ml) at 25° C. Stirring was continued for 20 hours. Water (1200 ml) was added and the mixture extracted with ether to give a crude oil which was purified by distillation (b.p. 102°/0.25) to give 1-(2-methoxyphenyl)cyclopropane carbonitrile.
