To a sealed tube was added 4-(aminomethyl)phenylboronic acid 1-1 (1.87 g, 10 mmol), 4-bromopyridazine 1-2 (1.58 g, 10 mmol), Pd(PPh3)4 (230 mg, 0.2 mmol), saturated Na2CO3 (15 mL), ethanol (15 mL) and toluene (45 mL). The reaction was heated to 110° C. and stirred for 2 hours. The reaction was cooled down to room temperature. The solvent was removed by rotary evaporation. The residue was dissolved in 10% methanol in DCM. The salt was removed by filtration. The filtrate was dried. The crude product was purified by silica-gel flash chromatography, eluted with 10% methanol in DCM to give (4-(pyridazin-4-yl)phenyl)methanamine 1-3 as off-white solid. MS m/z 186.2 (M+1).
