Participants

Reaction Steps

A mixture of 6-{[6-(2-Chloro-pyridin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl]-difluoro-methyl}-quinoline (see Example 100b) (50 mg, 0.122 mmol) in DMF (4 mL) and Zn(CN)2 (43 mg, 0.367 mmol) was degassed with house vacuum for ˜5 min, and tetrakis(triphenylphosphine)palladium (13.4 mg, 0.012 mmol) were then added. The mixture was microwaved at 190° C. for 20 min. Following the aqueous work up, solvent was removed by vacuo. The target compound, 21 mg (41%), was obtained by column purification. 1H NMR(CDCl3) δ 9.04 (dd, J=4.2, 1.6 Hz, 1H), 8.95 (d, J=5.12 Hz, 1H), 8.41 (d, J=9.8 Hz, 1H), 8.22-8.35 (m, 4H), 8.00-8.05 (m, 2H), 7.70 (d, J=9.8 Hz, 1H), 7.54 (dd, J=8.2, 3.8 Hz, 1H); MS (ES) m/z 400.3 (M+H+).
