Versuchsvorschrift
5-Ethyl 1-methyl (2E,4Z)-4-(1-aminoethylidene)pent-2-enedioate (10 g, 50 mmol) and DMF (30 mL) were mixed in one 100 mL flask, and the mixture was stirred at 165° C. for 14 hrs. The reaction mixture was cooled to room temperature, then filtered to give the crude product, which was washed with DMF and small amount of methanol to give 5 g (60% yield) of the pure product. LC-MS found: 182.1 (M+H)+.
