Procedure
To a mixture of 26-2 (0.622 g, 2.6 mmol) and sodium iodide (1.56 g, 10.4 mmol) in acetonitrile (7 ml) at ambient temperature in a 3-necked round bottom flask equipped with a nitrogen inlet and rubber septum was added dichlorodimethylsilane (0.63 ml, 5.2 mmol) via syringe. The resulting mixture was stirred 60 min. Saturated sodium bicarbonate solution (30 ml) was added and the mixture was extracted with ethyl acetate (2×90 ml). The combined organic fractions were washed with 10% sodium thiosulfate solution (30 ml), brine (30 ml), dried (sodium sulfate), and the solvent was evaporated under reduced pressure. The residue was purified by flash column chromatography on silica gel, eluting with ethyl acetate/hexane (1:6 increasing to 1:5), to give product 26-3 as a white solid, mp: 41.5°-43.5° C.
