After cooling, the mixture was concentrated in vacuo and the residue partitioned between dichloromethane (100ml) and water (100ml). The organic layer was separated and the aqueous solution extracted further with dichloromethane (2 x 100ml). The organic extracts were combined, dried with magnesium sulfate and concentrated in vacuo. The resulting liquid was distilled to give 8.5g of the desired compound, bp 128-45°C at 0.1 mmHg.
