Synthesis of 2-ethoxycarbonylmethyl-2-(3-substituted phenyl) cyclohexanone was examined by condensation of 2-(3-substituted phenyl) cyclohexanone with ethyl α-haloacetate in the presence of sodium amide or sodium hydride, and it was found that not only the expected alkylation but also the Darzens condensation took place in this reaction. The yield of alkylation decreased in the order of ethyl iodoacetate, bromoacetate, and chloroacetate.
