Reaction Steps

In a 100 ml three-necked flask equipped with a mechanical stirrer, dropping funnel, reflux condenser, and a nitogen-inlet tube, 1.5 gm (38 mmol) of 60% sodium hydride, 3.6 gm (36 mmol) of pinacolone, 3.0 gm (15.5 mmol) of dimethyl isophthalate, and 30 ml of anhydrous tetrahydrofuran were mixed with stirring under nitrogen stream and refluxed with heating for 6 hours. After cooling the reaction mixture, 10 ml of 2N aqueous hydrochloric acid was added the product was extracted with chloroform. The extract was dried over anhydrous sodium sulfate and the solvent was evaporated to give a crude product. Recrystallization using hexane afforded 3.1 gm of the target compound as colorless crystals (yield: 61%).
