Procedure
A mixture of 0.30 g (0.54 mmol) of 3-[3-(4-hydroxyphenoxy) propoxy]-5-(octadecyloxy)benzoic acid, 0.14 g (1.62 mmol) of sodium bicarbonate and 0.67 ml (10.8 mmol) of methyl iodide in 5 ml of DMF was stirred and heated at 40° for 48 hours. The solvent was removed at reduced pressure, the residue was extracted with ethyl acetate and the extract was washed with water. The dried extract was concentrated to a solid which was triturated with hexane and filtered to give 0.298 g (97% yield, mp 88°-90°) of 3-[3-(4-hydroxyphenoxy)propoxy]-5-(octadecyloxy)benzoic acid methyl ester.
