A general method for the synthesis of 8-arylamino- and 8-(2-benzothiazolylamino)-purines and their 1- and 3-deaza analogs is reported. The need for the presence of the desulfurizing agent in the preparation of the 8-arylamino derivatives is demonstrated and evidence for an intermediate thiourea is provided.
