実験手順
To a solution of methyl thioglycolate (91.0 mL, 1.0 mol) and piperidine (2 mL, 4.05 mmol) was added methyl acrylate (99.2 mL, 1.1 mol) dropwise. The reaction mixture was stirred at 50° C. for 2 h. The excess methyl acrylate and piperidine were then removed by distillation to afford methyl-3-(2-methoxy-2-oxoethylthio)-propanoate as a colourless oil (185 g, 96%). Without further purification, the crude product was used directly to the next step.
