Reaction Steps

To a solution of 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-iodonicotinamide (Stage 247.2, 300 mg, 0.654 mmol) and (3R,4R)-pyrrolidine-3,4-diol (88 mg, 0.850 mmol) in iPrOH (5 mL) was added DIPEA (0.228 mL, 1.307 mmol). The RM was stirred at 140° C. for 1 h and then 3 h at 130° C. The solvent was evaporated off under reduced pressure to give the crude product which was used directly without any further purification. UPLC-MS (Condition 3), tR=1.00 min, m/z=525.9/528.0 [M+H]+.
