Procedure

12.8 g (66 mmol) of 2-hexyloxyphenol, 23.3 g (73 mmol) of 16-bromohexadecan-1-ol and 20.0 g (99 mmol) of tri-n-butylphosphine were added to 350 mL of dehydrated methylene chloride followed by cooling with ice in the presence of argon. After adding 25.0 g (99 mmol) of 1,1′-(azodicarbonyl) dipiperidine a little at a time while stirring, 150 mL of methylene chloride were added. After stirring for 30 minutes at room temperature in the presence of argon, the reaction solution was refluxed for 6 hours. After cooling, the reaction solution was dropped into 100 mL of hexane and filtered. The filtrate was concentrated and purified by silica gel column chromatography to obtain 26.5 g of a clear liquid.
