Reaction Steps

To a 20 dram vial was added 6-chloro-N-((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)pyridazin-3-amine (1.8 g, 6.23 mmol, 1.0 equiv), 2-methoxypyridin-3-ylboronic acid (1.0 g, 6.54 mmol, 1.1 equiv), Cl2Pd(dppf) (350 mg, 0.43 mmol, 0.07 equiv), 2M potassium carbonate (8 mL, 15.5 mmol, 2.5 equiv), and dioxane (21 mL). The reaction was stirred and heated to 90° C. for 2 h and then diluted with water (20 mL) and ethyl acetate (50 mL). After transferring to a separatory funnel and shaking, the organic layer was separated from the aqueous layer and then washed with lithium chloride (1×20 mL). The organic layer was then dried over Na2SO4, filtered, and concentrated to give a crude solid that was purified by silica gel column chromatography to give N-((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)-6-(2-methoxypyridin-3-yl)pyridazin-3-amine (1.7 g, 77%) as an off-white solid.
