When the solid is all dissolved, the solution is extracted with ether (3×100 ml). The ether solution is washed with brine, dried over potassium carbonate and concentrated under vacuum to yield 5.16 g (77%) of a tan oil. This oil is distilled at 140° C. under 0.005 ml vacuum to afford the product, a colorless liquid.
