Synthesis of 2, 4-diamino-6-(alpha-hydroxybenzyl)-1, 3, 5-triazines: a new method for formation of s-triazines

A new synthetic method for preparation of 6-substituted 2, 4-diamino-1, 3, 5-triazines (2a-d) will be presented. Thus, cyclization of 2-hydroxy-2-phenyl-acetamides 1a-d with guanidine afforded 2, 4-diamino-6-(α -hydroxy-benzyl)-1, 3, 5-triazines 2a-d. In addition to compounds 2a-d 2-imino-5-phenyl-oxazolidin-4-ones 3a-d were obtained. Amides 1 were prepared in a few steps starting from appropriate benzaldehydes. The structure of triazine 2a was additionally proved by X-ray crystallography.
