2,3-Pyrazinecarboxylic anhydride Chemical Properties,Uses,Production
Uses
2,?3-?Pyrazinedicarboxylic Anhydride is a reagent used in the synthesis of highly potent and selective abietane type diterpenoid amides.
Synthesis
Pyrazine-2,3-dicarboxylic acid (4.0 g, 23.8 mmol) was dissolved in acetic anhydride (30 mL).The reaction mixture was refluxed for one hour, and subsequently cooled down to 0 °C in ice bath.The obtained crystals of pyrazine-2,3-dicarboxylic anhydride were filtered off (yield 70%).
