To a magnetically stirred solution of 69 mg (0.6 mmol) of trifluoroacetic acid, in 2 ml of dry methylene chloride, at 0° C., 0.046 ml (0.6 mmol) of dry DMF was added and then 0.3 ml (0.6 mmol) of 2.0 M solution of oxalyl chloride in methylene chloride, dropwise. The reaction mixture was stirred for 20 min and then a solution of 172 mg (0.6 mmol) of arachidonyl amine in 2 ml of methylene chloride was added and the reaction was stirred for 2 hrs at ambient temperature. The product was purified with silica gel column chromatography (eluents: petroleum ether/ethyl acetate, up to 50% ethyl acetate). Evaporation of the solvent, followed by Millipore filtration of a CH2Cl2 solution of the product gave 153 mg (0.4 mmol, 67% yield) of arachidonyl-amine-trifluoroacetate as a colorless oil.
