Reaction Steps

K3PO4 (191 mg, 0.9 mmol) and Pd(PPh3)4 (17.33 mg, 0.015 mmol) were added to a solution of 6-Chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-iodonicotinamide (Stage 25.2, 138 mg, 0.3 mmol) and 4-methyl-1-(tetrahydro-2H-pyran-2-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (131 mg, 0.45 mmol) in toluene (1.5 mL) under an argon atmosphere in a vial, which was sealed and heated at 110° C. for 18 h. The RM was poured into 20 mL water and extracted with EtOAc. The combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a residue which was purified by flash chromatography (RediSep® Silica gel column, n-heptane/EtOAc, from 5 to 50% EtOAc) and crystallized from n-heptane to afford the title compound as an off-white powder. HPLC (Condition 4) tR=6.8 min, UPLC-MS (Condition 3) tR=1.26 min, m/z=495 [M−H]−.
