Versuchsvorschrift
The title compound was prepared in an analogous fashion to that described in Stage 13.1 using 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-iodonicotinamide (Stage 25.2) and 4-fluoro-5-(tributylstannyl)-1H-pyrazole to afford an off-white powder. HPLC (Condition 4) tR=5.69 min, UPLC-MS (Condition 3) tR=1.09 min, m/z=415 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm.
