3-Chloro-4,5-dimethyl-6-((R)-3-methyl-piperazin-1-yl)-pyridazine (1.20 g, 4.88 mmol), 5-chloro-pyrazine-2-carboxylic acid methyl ester (946 mg, 5.37 mmol), triethylamine (3.40 mL, 24.4 mmol), and 1,4-dioxane (10 mL) are combined in a 100 mL round-bottom flask fitted with a reflux condenser and heated to 80° C. for 24 h. The reaction is then allowed to cool to room temperature and stirred for 48 h. A beige solid precipitates during this time which is isolated by filtration, rinsing with H2O. The precipitate is dried in vacuo to afford the title compound (1.30 g, 71%).
