We have obtained a series of 3-aryl-7-arylidene-3,4-dihydro-2H-[1,3] thiazolo[3,2-a][1,3,5]triazin-6(7H)-ones by means of heterophase aminomethylation of 2-amino-5-arylidene-1,3-thiazol-4(5H)-ones with aqueous formaldehyde and aromatic amines in benzene or toluene. We explain the effect of substituents in the heterocyclic substrate and the aryl amine on the efficiency of the process within a detailed scheme for one of the possible aminomethylation reaction routes.
