Methyl iodide → HCID 54427130, compound

Participants

Reaction Steps

A solution of 19.9 gm (0.059 mol) of [1-(2'-chloro-4-biphenylyl)-ethylsulfinyl]-acetic acid and 12.5 gm (0.088 mol) of methyl iodide in 120 ml of dry dimethyl sulfoxide was admixed with 12.2 gm (0.088 mol) of dry potassium carbonate, and the mixture was stirred at room temperature for 19 hours. The crude reaction product was precipitated with water and extracted with ethyl acetate (yield: 23.1. gm). For purification, the obtained crude product was purified by chromatography on 1200 gm of silicagel with cyclohexane ethyl acetate = 1/1. The combined fractions with an Rf -value of 0.23 (on carrier 2) were combined and evaporated, leaving 6.2 gm (31.2% of theory) of the title compound; oil, Rf -value: 0.23 on carrier 1 with cyclohexane/ethyl acetate = 1/1.
