Heteroaryl amines are efficiently coupled (in two hours) to arylhalides with catalytic Pd 2 (dba) 3 and Xantphos to provide the corresponding biaryl amines under microwave and standard thermal conditions. The use of organic-soluble sodium phenolate (NaOPh) as the stoichiometric base promotes facile coupling of a variety of substrates in excellent yields.
