A new, effective one-pot synthesis of the 6,N2-diaryl-1,3,5-triazine-2,4-diamines undermicrowaveirradiation was developed. The method involved an initial three-component condensation of cyanoguanidine, aromaticaldehydes, and arylamines in the presence of hydrochloric acid. Without isolation, the resulting 1,6-diaryl-1,6-dihydro-1,3,5-triazine-2,4-diamines were treated with a base to initiate Dimroth
