Procedure

Jones reagent (a 2.67M solution in sulphuric acid; 1.32 ml, 3.5 mmol) was added dropwise to a solution of 4-hydroxytridec-2-ynoic acid (531.8 mg, 2.4 mmol) in acetone (10 ml) at 0° and the reaction mixture was maintained at 0° for 70 minutes. The mixture was quenched with ethanol (1 ml) and dried with magnesium sulphate. On evaporation, the title acid was obtained as a colorless oil.
