Crystal and molecular structure of 2-(2-methoxycarboxyl) phenyloxy-5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine

The crystal structure of the title compound has been determined by single c rystal X-ray diffraction analysis. C15H14N4O3, M-r = 298. 30, monoclinic, s pace group P2(1)/n, a = 9. 483 (9), b = 11. 078 (9), c = 13. 700 (9) Angstr om, beta = 100. 19 (7)degrees, V = 1417 (4) Angstrom(3), Z = 4, D-x = 1. 39 9 g. cm(-3), mu = 0. 0942 mm(-1); F(000) = 624, final R = 0. 074 and R-w = 0. 074 for 1502 observed reflections [I greater than or equal to 3 sigma(I) ]. The results show that all ring atoms in the triazolopyrimidinyl moiety w ere coplanar with strong tensile force, which might be an important active site.
