Reaction Conditions

Reaction Steps

The 2-methanesulfonyloxypentadecane (34.4 g, 102 mmol) was reacted with 4-iodophenol (22.7 g, 103 mmol) and potassium carbonate (14.3 g, 103 mmol) in DMF (200 ml) as per 2-(4-iodophenoxy)decane except that the temperature of the oil bath was maintained at 80° C. for 15 hrs and increased to 86° C. with stirring for an additional 24 hrs. At the end of this period, NMR spectral analysis indicated that the reaction was complete. The reaction mixture was processed as for 2-(4-iodophenoxy)decane except with four times the volumes to provide a light yellow oil. Flash column chromatography (silica, hexanes) yielded 2-(4-iodophenoxy)pentadecane (18.9 g, 43.0%) as a clear oil.
