실험 절차

A mixture of (RS) 2-hydroxy-2-(thien-3-yl)acetic acid (prepared as described in Akiv. Kemi., 58, 519, 1957) (6.32 g), methyl iodide (17 g) and potassium carbonate (6 g) in acetone was refluxed for 2 hours, evaporated under reduced pressure and the residue partitioned between ethyl acetate and water. The organic extracts, after drying over magnesium sulphate, were evaported to leave the title compound as a yellow oil (4.49 g, 67%).
