実験手順
294 gm (1.17 mol) of 1-(2'-chloro-4-biphenylyl)-1-chloro-ethane and 149.2 gm (1.4 mol) of thioglycolic acid methyl ester were dissolved in 1 liter of dimethyl sulfoxide, and 194.3 gm (1.4 mol) of potassium carbonate were added to the solution in small portions, while stirring vigorously and cooling on ice water. After stirring the mixture for 4 hours, 3 liters of water were added. The reaction product was extracted with toluene, and after washing the extract with water and drying it over magnesium sulfate, the solvent was removed in vacuo. Yield: 359:0 gm (95.5% of theory). Rf -value: 0.6 on carrier 1 with cyclohexane/ethyl acetate=4:1.
