Participants

Reaction Steps

To a solution of ethyl cis-docosahexaenoate (5 g, 14.0 mmol) in methanol (100 mL) was added an aqueous solution of NaOH (6 g, 150 mmol, in 20 mL of water) at rt and stirred for 1.5 h. The reaction mixture was poured into ice cooled water and acidified with dil. HCl. The solution was extracted with DCM (3×50 mL) and the combined layer was washed with water, brine and dried over sodium sulfate. The solution was filtered and the solvent evaporated to give the acid (4.2 g, 91%) as an oil; LCMS (ESI, negative ion mode): m/z 327 (M-H)−.
