Procedure

A solution of 1,3-dicyclohexylcarbodiimide (23.7 g) and 4-(N,N-dimethylamino)pyridine (15.9 g) in methylene chloride (200 ml) was added to a solution of 1-(z,z,z-octadeca-6,9,12-trienoyloxy)-3-hydroxypropane (33.6 g) and z-octadeca-9-enoic acid (30 g) in methylene chloride (400 ml) under nitrogen at room temperature. On completion of reaction as evidenced by tic analysis the solution was diluted with hexane, filtered, concentrated and purified by dry column chromatography to yield 1-(z,z,z-octadeca-6,9,12-trienoyloxy)-3-(z-octadeca-9-enoyloxy)propane as a free flowing pale yellow oil.
