Reaction Steps

Ethanol (4.39 mL, 75.2 mmol) was added dropwise to a suspension of sodium hydride (0.607 g, 15.2 mmol, 60% in mineral oil) in a flask that was held in an ice bath. Ten minutes after complete addition, a mixture of 1-cyclobutylethanone (1.5 mL, 14 mmol, Aldrich) and diethyl oxalate (2.01 g, 13.8 mmol, Aldrich) was added dropwise. After stirring overnight, 4.0M sulfuric acid in water (0.00759 L, 30.4 mmol) was added. The product was extracted into diethyl ether. The combined organic extracts were washed with water and brine, dried over sodium sulfate, filtered and concentrated. The material was used without further purification in Step B.
