Reaktionsschritte

To 6-bromo-pyridazin-3-ylamine (521, 0.85 g, 0.0049 mol) in acetonitrile (30.0 mL) were added 4-chlorobenzaldehyde (40, 0.82 g, 0.0058 mol), triethylsilane (4.0 mL, 0.025 mol) and trifluoroacetic acid (2.0 mL, 0.026 mol). The reaction was heated to reflux for 4 hours, then poured into water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated and washed with ethyl acetate to give a white solid (522, 1.0 g). MS (ESI) [M+H+]+=298.3, 300.2.
