6-Chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-iodonicotinamide (Stage 48.3, 257 mg, 0.560 mmol), (1-(tert-butoxycarbonyl)-5-(dimethylcarbamoyl)-1H-pyrrol-2-yl)boronic acid (Stage 73.2, 200 mg, 0.709 mmol), Pd(Ph3P)4 (64.7 mg, 0.056 mmol), Na2CO3 (237 mg, 2.240 mmol), water (560 μL) and DME (2.240 mL) were added to a MW vial, which was sealed, evacuated/purged with argon and stirred at 80° C. for 16 h. The RM was diluted with MeOH (1 mL)/DCM (2 mL), treated with Si-Thiol (194 mg, 0.280 mmol), filtered and the filtrate was evaporated off under reduced pressure to give a residue which was purified by flash chromatography (RediSep® Silica gel column, 12 g, cyclohexane-DCM (4:1)/EtOAc, from 5% to 50% EtOAc) to yield the title product as a white solid.
