Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
2-Dimethylamino methylenechromanone 1 reacted with 4H-1,2,4-triazol-3-amine in acetic acid to give only one isolated product which was identified by X-ray study as 6H-chromeno[3,4-e][1,3,4]triazolo[2,3-a]pyrimidine. The molecular structure of 3, C12H8N4O, was determined to be monoclinic, P2(1)/c, a = 16.3875(5), b = 8.8378(3), c = 13.8392(5) angstrom, beta = 101.190(1)degrees, V = 1966.22(11) angstrom(3), Z = 8.
