3-Bromo-4-((3S,4S)-3,4-dihydroxypyrrolidin-1-yl)-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 28.1, 100 mg, 0.217 mmol), (1-(tert-butoxycarbonyl)-5-cyano-1H-pyrrol-2-yl)boronic acid (Stage 29.1, 103 mg, 0.436 mmol), Pd(PPh3)2Cl2 (15.22 mg, 0.022 mmol), Na2CO3 (92 mg, 0.867 mmol), DME (920 μL), water (263 μL) and EtOH (131 μL) were added to a MW vial, which was sealed, evacuated/purged with argon and the RM was stirred at 70° C. for 16 h. MeOH (0.5 mL) was added and the RM was subjected to MW irradiation at 150° C. for 5 min. The RM was diluted with DME (3 mL), treated with Si-Thiol (Silicycle, 1.44 mmol/g, 90 mg, 0.130 mmol), centrifuged, the supernatant was filtered and the solvent was evaporated off under reduced pressure to give a residue which was purified by flash chromatography (RediSep® Silica gel column, 12 g, DCM/MeOH-1% NH4OH, from 1% to 10% MeOH-1% NH4OH) followed by preparative SFC (Column NH2, from 26% to 31% in 10 min) to yield the title compound as an off-white solid.
