실험 절차

The mesylate of 3-nonanol (11.5 g, 51.9 mmol), triiodophenol (24.5 g, 51.9 mmol) and potassium carbonate (7.18 g, 51.9 mmol) were reacted in dry DMF (200 ml) as per 2-(2,4,6-triiodophenoxy)-pentadecane except at an oil bath temperature of 87° C. for 16 hrs. The reaction was processed as for 2-(2,4,6-triiodophenoxy)-pentadecane to provide a light brown oil. Flash column chromatography (silica, hexanes) provided 3-(2,4,6-Triiodophenoxy)-nonane (20.9 g, 67%) as a clear viscous oil. Title Compound: 1H (300 MHz) and 13C (75 MHz) NMR spectra were consistent with the desired structure. FAB/MS M+ 598. Calculated for C15H21I3O: C, 30.13; H, 3.54; I, 63.66. Found: C, 30.54, H, 3.51; I, 63.58.
