Versuchsvorschrift

A mixture of 18.5 parts of 2,4-dichlorobenzeneacetonitrile and 180 parts of N,N-dimethylformamide is stirred and cooled in an ice-bath while nitrogen gas is introduced. 3.2 Parts of a sodium hydroxide solution 78% are added portionwise and the whole is stirred for one hour. Then there are added dropwise, during a one hour-period, 17.8 parts of (bromomethyl)cyclohexane while still cooling and while nitrogen gas is still introduced. Upon completion, stirring is continued for 2 hours at room temperature. The reaction mixture is poured onto water. The precipitated product is filtered off and triturated in a mixture of methanol and water. The product is filtered off and dried, yielding 25.5 parts of 2,4-dichloro-α-(cyclohexylmethyl)benzeneacetonitrile; mp. 58.8° C.
