A mixture of 4,6-dichloropyrimidine (5 g, 34 mmol), isoquinolin-5-amine (5.3 g, 37 mmol), 2′-(dimethylamino)-2-biphenylyl palladium (II) chloride dinorbornylphosphine complex. [see Angew. Chem., 2002, 41, 3668; CAS number 359803-53-5] (940 mg, 2 mmol) and sodium tert-butoxide (4.8 g, 50 mmol) in p-xylene (100 ml) was degassed thoroughly and heated under nitrogen at 100° C. for 16 hours. The cooled reaction mixture was purified by column chromatography over silica (eluant 1% MeOH in DCM) to give the title compound (1.5 g, 17%).
