3-Benzoyl-2-hydroxy-3a-[(3-methylquinoxalin-2-yl)methyl]-1H-pyrrolo[2,1-c][1,4]benzothiazine-1,4(3aH)-dione

Abstract

The reaction of 3-benzoylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-trione with 2,3-dimethylquinoxaline afforded 3-benzoyl-2-hydroxy-3a-[(3-methylquinoxalin-2-yl)methyl]-1H-pyrrolo[2,1-c][1,4]benzothiazine-1,4(3aH)-dione in a moderate yield. The compound was fully characterized.
