Procedure

A mixture of the iodide from Step 1 (3.7 g, 8.5 mmol) and potassium cyanide (5.5 g, 85 mmol) in DMF (40 mL) was stirred at room temperature for 45 minutes. There was added water (50 mL) and brine (100 mL) and the mixture was extracted with 1:1 ethyl acetate-hexane (4×100 mL); the combined extracts were washed with water (2×50 mL) and brine (1×50 mL), dried and evaporated. The crude residue was chromatographed on silica gel eluting with a 1:2 mixture of ether-ethyl acetate to afford the title compound as a yellow oil.
