Procedure

In 20 ml. of diethyl ether was dissolved 3.0 g. of the above-obtained 3,7,11,15-tetramethyl-2,4,6,10,14-hexadecapentaenoic acid. To this solution was added 1 g. of triethylamine, and further added 1.1 g. of ethyl chlorocarbonate under stirring at room temperature. After 10 minutes, gaseous ammonia was introduced into the solution. The reaction liquid was washed with three 10 ml. portions of water, dried over magnesium sulfate, and evaporated to remove the solvent. The residue was purified by alumina column chromatography and crystallized from a mixture of acetone and n-hexane (1:2). There was obtained 1.7 g. of the desired product as pale yellow crystals.
