Crystal structure of 6-amino-4-(3-bromo-4-meth-oxy-phen-yl)-3-methyl-2,4-di-hydro-pyrano[2,3-c]pyrazole-5-carbo-nitrile dimethyl sulfoxide monosolvate.
In the pyrazole mol-ecule of the title solvate, C15H13BrN4O2·C2H6OS, the dihedral angle between the benzene ring and the mean plane of the di-hydro-pyrano[2,3-c]pyrazole ring system [r.m.s deviation = 0.031 (2) Å] is 86.71 (14)°. In the crystal, the pyrazole mol-ecules are linked by N-H⋯N hydrogen bonds, forming a layer parallel to (10-1). The pyrazole and dimethyl sulfoxide mol-ecules are connected by an N-H⋯O hydrogen bond.
