Reaction Conditions

Reaction Steps

A mixture of N-(17-carboxyheptadecyl)maleamic acid (400 mg, 1.01 mmoles), 2.83 ml of acetic anhydride, and anhydrous sodium acetate (41.0 mg, 0.50 mmoles) was heated at 100° C. with stirring for 1 hour. The reaction mixture was allowed to cool, then poured onto ice and stirred for 1 hour. The resulting mixture was extracted with chloroform. The separated organic layer was washed with water and then with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, concentrated under reduced pressure and isolated and purified by silica gel column chromatography [eluent: mixture of benzene and chloroform (volume ratio: 1:1)], to give 18-maleimidooctadecanoic acid (172 mg, 45%) having the following properties.
