(±)-3-(5-Amino-3-methyl-1-phenyl-1H-pyrazol-4-yl)-2-benzofuran-1(3H) -one

Abstract

In the title compound, C18H15N3O2, the benzofuran ring system is essentially planar, the rings making a dihedral angle of 0.57 (9)°. The phenyl, furan and benzene rings subtend dihedral angles of 47.07 (10), 85.76 (7) and 86.04 (7)°, respectively, with the pyrazole ring. In the crystal, molecules are linked by weak N - H...N, N - H...O and C - H...O interactions, generating edge-fused R 4 4(20), and R 1 2(7) rings linked into sheets which are parallel to (010).
