Versuchsvorschrift
5-bromo-3-chloro-2-hydrazinylpyrazine 1′-1 (945 mg; 3.51 mmol) is dissolved in 12 ml trimethyl orthoacetate and heated up to 130° C. for 1 hour. The solution is diluted with water and extracted with EtOAc. The organic phase is then purified with flash chromatography: cHex/EtOAc=70%/30% to 55%/45% within 10 column volumes.
