Versuchsvorschrift

A solution of 5-fluoro-2-(3-(piperidin-4-ylidenemethyl)phenoxy)pyridine trifluoroacetate (0.466 g), phenyl pyridazin-3-ylcarbamate (0.274 g, 1.40 equiv), and triethylamine (0.634 mL, 5.00 equiv) in dimethyl sulfoxide (2.0 mL, 0.30 M) was heated to 65° C. for 2 h. The reaction was cooled to room temperature. Water was added and then the solution was extracted with ethyl acetate (3 times). The organic extracts were combined and washed with water, dried over magnesium sulfate, filtered, and concentrated. The residue was purified on a 12 g silica gel column using 20-50% ethyl acetate/dichloromethane over 60 minutes as the eluent to give the title compound as a yellow foam. 0.155 g, 42% yield. 1H NMR (400 MHz, CDCl3) δ ppm 2.46 (2H, t, J=5.5 Hz), 2.59 (2H, t, J=5.5 Hz), 3.61 (2H, t, J=5.8 Hz), 3.71 (2H, t, J=5.8 Hz), 6.39 (1H, s), 6.84-6.99 (3H, m), 7.02 (1H, d, J=7.8 Hz), 7.34 (1H, t, J=7.8 Hz), 7.39-7.54 (2H, m), 8.02 (1H, d, J=3.1 Hz), 8.47 (1H, d, J=8.6 Hz), 8.74 (1H, d, J=3.5 Hz).
