α-dichlorobenzyl)amino)butanenitriles with sodiummethoxide in methanol resulted in novel methyl N-(2-chloro-1-(cyanomethyl)ethyl)benzimidates, although in low yields. The latter γ-chloro nitriles were smoothly converted into methyl N-(2-cyanocyclopropyl)benzimidates as precursors of biologically relevant β-ACC derivatives through a 1,3-cyclization protocol by reaction with potassium tert-butoxide in THF
