Procedure

A mixture of 4-iodo-1-methoxy-phthalazine-6-carboxylic acid (3-trifluoromethyl-phenyl)-amide (0.128 g, 0.27 mmol), K2CO3 (0.075 g, 0.54 mmol), water (0.5 mL), toluene (3 mL), methanol (3 mL), 3-pyridineboronic acid (0.04 g, 0.325 mmol), Pd(PPh3)4 (0.094 g, 0.081 mmol) was heated to 65° C. for 2 hour. The reaction was cooled, filtered through celite, rinsed with methanol and concentrated. The residue was taken up in EtOAc, washed with sat. aq. NaHCO3 and dried (Na2SO4). Column chromatography (Hex/EtOAc) afforded 1-methoxy-4-pyridin-2-yl-phthalazine-6-carboxylic acid (3-trifluoromethyl-phenyl)-amide (57 mg), m/z 425.01
