Triazolopyrazine Series

 

AEW 86-1, i.e. 2-chloro-6-hydrazinylpyrazine (1.218 g) was sirred in AcOH (0.41 mL) in MeCN (12.24 mL) and 4-formylbenzonitrile (1.10 g) was added to the orange suspension and the resulting reaction mixture stirred at room temperature for 2 h. No SM visible on TLC, and clear product spot observed. The solvent was removed under vacuum to yield an orange/brown solid (2.375 g, xxx crude yield) which was investigated with 1H NMR analysis (EO 2-1 1H NMR)   TLC (30% EtOAc in Hexane under UV)   Hazard and Risk Assesment   [data]7669[/data]
