Procedure

Maleic anhydride (39.4 g, 0.40 mol) was partly dissolved in toluene (1 l) to form a milky suspension. N-hexylamine (53 ml, 0.40 mol) was diluted with toluene (500 ml) and added dropwise over a period of 1.5 h. After 2 h, the reaction mixture was filtered and the title compound was obtained as a Nvhite solid (76.4 g, 96%) after drying for 16 h in a vacuum oven at 40° C.
