In the pyrazole molecule of the title solvate, C15H13BrN4O2·C2H6OS, the dihedral angle between the benzene ring and the mean plane of the dihydropyrano[2,3-c]pyrazole ring system [r.m.s deviation = 0.031 (2) Å] is 86.71 (14)°. In the crystal, the pyrazole molecules are linked by N—H...N hydrogen bonds, forming a layer parallel to (10-1). The pyrazole and dimethyl sulfoxide molecules are connected by an N—H...O hydrogen bond.
