Reaction Steps

5,8-Dibromo-[1,2,4]triazolo[1,5-a]pyrazine (0.1 g, 0.36 mmol), (R)-1-Benzyl-pyrrolidin-3-ylamine (0.07 g, 0.396 mmol, 1.10 equiv.) and DiPEA (0.15 mL, 0.72 mmol, 2.00 equiv.) are mixed in isopropanol (5 mL) under nitrogen. The reaction is heated to 85° C. until completion of the reaction (typically 5 h). The mixture is then allowed to cool down to room temperature and diluted with diethyl ether, causing the precipitation of the title compound as a solid that is used without further treatment.
