Komponenten

Versuchsvorschrift

To 2,6-dichloropyrazine (150 mg, 1.007 mmol) in 1,4-dioxane (1.0 mL) was added 1-methylpiperazine (121.0 mg, 0.13 mL, 1.208 mmol) followed by triethylamine (203.8 mg, 0.281 mL, 2.014 mmol). The reaction mixture was stirred at room temperature for 24 h then concentrated. Purification by flash column chromatography on silica gel using 100:5:1 EtOAc/MeOH/NH4OH (0 to 100%) in EtOAc provided the product. LCMS-ESI+ calc'd for C9H14ClN4 (M+H+): 213.1; Found: 213.2 (M+H+).
