Procedure
This compound was subjected to TLC analysis [silica gel plate, developing solvent:CHCl3 -MeOH-H2O (90:10:1)]. As a result, a single spot was obtained by the detection with iodine and a 0.2% ninhydrin reagent. The obtained 4-(N-5,8,11,14,17-eicosapentaenoylamino)benzylamine (813 mg, 2 mmol) and Et3N (204 mg, 2 mmol) were dissolved in anhydrous THF (10 ml), and 2,6-diisopropylphenyl isocyanate (406 mg, 2 mmol) was added. The mixture was reacted for about 2 hours under cooling in a nitrogen stream, and concentrated under reduced pressure. The obtained concentrate was dissolved in a small amount of CHCl3 and applied to an SiO2 (800 g) column activated with CHCl3 in advance, which was followed by elution with CHCl3 (600 ml) and CHCl3 -MeOH (98:2, 800 ml) in this order. The objective fractions were recovered from the obtained eluate fractions based on TLC analysis as an index, and concentrated to give the objective compound (1.07 g, yield 88%).
