Reaction Steps

A mixture of 4-iodo-1-methoxy-phthalazine-6-carboxylic acid (3-trifluoromethyl-phenyl)-amide (0.123 g, 0.26 mmol), K2CO3 (0.072 g, 0.52 mmol), water (0.5 mL), toluene (3 mL), methanol (3 mL), phenylboronic acid (0.035 g, 0.286 mmol), Pd(PPh3)4 (0.09 g, 0.078 mmol) was heated to 65° C. for 1 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). Chromatography (Hex/EtOAc) afforded 1-methoxy-4-phenyl-phthalazine-6-carboxylic acid (3-trifluoromethyl-phenyl)-amide (89 mg), m/z 424.05.
