Reaction Steps
2-Chloro-5-nitropyridine (0.97 g, 5.5 mmol), ethyl 5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine-3-carboxylate (1.0 g, 5.1 mmol), and diisopropylethylamine (2 mL) were mixed in acetonitrile (5 mL), and heated to 80° C. for one h. The mixture was poured into water, and the precipitate was collected by filtration. The precipitate was washed with water, then by ether, and dried in a vacuum oven overnight to give 1.2 gram of product C-12 (75% yield).
