The regioselectivearylation at position 4 of 4-bromo-6-chloro-3-phenylpyridazine has been performed using a Suzukicross-couplingreaction. This route allows access to a wide-ranging series of pharmacologically useful pyridazine derivatives and confirms the usefulness of chloropyridazines as a masking group for the carbonyl moiety in cross-couplingreactions involving 5-bromo-3(2H)-pyridazinones.
