The general procedure was carried out using maleic anhydride (20.59 g, 210 mmol), 1,3-cyclohexanebis(methylamine) (14.22 g, 100 mmol), sodium acetate (1.64 g, 20 mmol), and acetic anhydride (22.46 g, 220 mmol). The resulting compound was purified by column chromatography (98:2 DCM:EtOAc), and the product obtained as a white solid (3.55 g/12%).
