2-formyl-6-methoxyphenyl oleate

DMAP (0.06 g, 0.5 mmol) was mixed with EDC.HCl (1.25 g, 6.5 mmol) in acetonitrile (25 mL), added with ortho-vanillin and oleic acid. The mixture was heated under reflux for one hour and was monitored by TLC. It was extracted with haxane and ethyl acetate. The resulting product was then washed with 1 M aqueous HCl twice, aqueous NaHCO3 twice, water and NaCl twice. MgSO4 was added to dry it and and the solvent was removed with rotary evaporator. Finally 2-formyl-6-methoxyphenyl oleate was formed.
