4-Hy­droxy-3,5-dimeth­oxy-N-{4-[(5-methyl-1,2-oxazol-3-yl)sulfamo­yl]phen­yl}benzamide methanol monosolvate

The title compound, C₁₉H₁₉N₃O₇S·CH₃OH, was synthesized from syringic acid and sulfamethoxazole. The benzene rings make a dihedral angle of 41.8 (1)° and the isoxazole ring is twisted by 74.3 (1)° from the central benzene ring. The crystal packing features O—H...O and O—H...N hydrogen bonds in which the hy­droxy groups from the main mol­ecule and methanol solvent mol­ecules serve as donor groups.
