Cleavage of 2-(Arylamino)-4,6-dimethoxypyrimidines to yield arylguanidines

A novel method for the synthesis of aryl-substituted guanidines in good overall yields is presented; it consists of the acidic cleavage of 2-(arylamino)-4,6-dimethoxypyrimidines, which were prepared by coupling aryl bromides with 2-amino-4,6-dimethoxypyrimidine. This methodology introduces a new means of protection for the guanidine functionality. Copyright

Formation of pyrimidin-2-ylcyanamide and 2-aminopyrimidine in the reaction of aniline derivatives with cyanamide and dimethylamino-1-pyridyl-2-propenone

Substituted o- and p-nitroanilines and m-benzylaminoanilines in the reaction with cyanamide failed to yield the corresponding arylguanidines, and in the presence of 3-dimethylamino-1-(3-pyridyl)-2-propen-1-one formed 4-pyridyl-substituted pyrimidin-2-ylcyanamides and 2-amino-pyrimidines.
