0.084 g 1-amino-5-(2,6-dioxopiperidin-3-yl)-5H-thieno(3,4-c)pyrrole-4,6-dione was dissolved in 10 mL of acetic anhydride and refluxed for 6 h. The reaction mixture was cooled and evaporated to dryness. The remaining residue was purified on silica gel column chromatography to yield a solid (0.067 g). MS (m/z): 320 (M−1)+.
