Abstract: 3-Substituted 1,2,4-triazole derivatives (5, 9, 13, 16b, 19), pyrimidinium salts (21), triazines (24), and aryl methylene hydrazono pyrazolopyrano-pyrimidine (27a,b) which are rearranged in basic medium to 30a,b, were afforded via the reaction of 6-amino 1,4,5,6-tetrahydro-5-imino-3-methyl-1-phenyl-4 (pchlorophenyl) pyrazolo [4', 3' : 5,6]-pyrano [2,3-d] pyrimidine (3) with different reagents.
