Versuchsvorschrift

The title compound was prepared in an analogous fashion to that described in Example 92 using N-(4-(chlorodifluoromethoxy)phenyl)-6-(3-hydroxyazetidin-1-yl)-5-iodonicotinamide (Stage 88.1) and 4-fluoro-5-(tributylstannyl)-1H-pyrazole. After purification by flash chromatography on silica gel, the residue was dissolved in MeCN (2 mL), sonicated and then stirred at RT for 90 min. The resulting suspension was filtered, washed with MeCN (3 mL) and dried to afford the title product as a white solid. HPLC (Condition 7) tR=5.72 min, UPLC-MS (Condition 8) tR=0.93 min, m/z=454.1 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 3.53-3.61 (m, 2H) 3.91-4.01 (m, 2H) 4.37-4.47 (m, 1H) 5.57 (br. s, 1H) 7.33 (d, J=8.99 Hz, 2H) 7.83-7.97 (m, 3H) 8.04 (d, J=1.96 Hz, 1H) 8.78 (d, J=1.96 Hz, 1H) 10.23 (br. s, 1H) 13.03 (br. s, 1H).
