Reaction Conditions

Reaction Steps

370 parts of ammonium chloride solution 0.78N are stirred and heated to reflux. Then there are added 37 parts of iron-powder, followed by the dropwise addition of a solution of 37 parts of 2,4-dichloro-α-[2-chloro-4-(hydroxyimino)-5-methyl-2,5-cyclohexandien-1-ylidene]benzeneacetonitrile in 333 parts of methylbenzene. Upon completion, stirring at reflux is continued overnight. The reaction mixture is cooled to 60° C, filtered and the filter-cake is washed with tetrahydrofuran. The filtrate is dried, filtered and evaporated. The residue is converted into the hydrochloride salt in 2,2'-oxybispropane and 2-propanol, yielding 4-amino-2-chloro-α-(2,4-dichlorophenyl)-5-methylbenzeneacetonitrile hydrochloride.
