Reaction Steps

In a 50 mL round bottom flask, 6-{4-[3-((R)-2-methyl-pyrrolidin-1-yl)-propoxy]-phenyl}-2H-pyridazin-3-one (250 mg, 0.71 mmol), 2-bromopyridine (105 μL, 1.07 mmol), copper(I)iodide (13.6 mg, 0.07 mmol), and potassium carbonate (296 mg, 2.14 mmol) in dimethylformamide (10 mL) was heated to reflux 14 h. The reaction was cooled and water (20 mL) was added. The sticky solids were filtered off and then partitioned between methylene chloride and water, separated, and dried over MgSO4. Purification with silica gel chromatography eluting with methylene chloride/methanol (95:5) produced 10 mg (2.4%) oil. MS m/z 391 (M+H).
