実験手順

To the 2,3-dimethyl succinic acid (5.13 g, 35.1 mmol), was added acetyl chloride (8.27 g, 7.49 mL, 105 mmol) at room temperature. The reaction mixture was refluxed at about 65° C. for 2 hrs. Workup consisted of concentration in vacuo, and drying in high vacuo. The desired product (4.95 g, with a little impurity of acetic acid) was obtained as a white solid.
