反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 31.8 g. (0.3 mol.) of thioacetic acid methyl ester are added to 150 ml. (0.3 mol.) of 2N sodium methylate solution. 22.6 g. (0.3 mol.) of chloroacetonitrile dissolved in 30 ml. of methanol are added dropwise while cooling and stirring. It is stirred overnight then refluxed for 30 minutes. The reaction mixture is cooled and the solvent is evaporated. 100 ml. of water are added to the residue and the aqueous solution is extracted twice with ether. The combined ether extracts are decolorized with activated carbon and dried with magnesium sulfate. The ether is distilled off and the residue is distilled under vacuum. 30.5 g. of 2-[(cyanomethyl)thio]-acetic acid methyl ester are obtained b.p.10mm 132°-134°. while cooling It is stirred overnight then refluxed for 30 minutes The reaction mixture is cooled the solvent is evaporated of water are added to the residue the aqueous solution is extracted twice with ether dried with magnesium sulfate The ether is distilled off the residue is distilled under vacuum
