To a sealable vial was added N-(4-bromo-2-fluorobenzyl)-5-((5-methylpyridin-2-yl)methoxy)-2-nitroaniline (700 mg, 1.57 mmol) RuPhos precatalyst (234 mg, 0.314 mmol) and RuPhos (149 mg, 0.314 mmol), 3,3-difluoroazetidine hydrochloride (610 mg, 4.71 mmol) and N2 sparged THF (7.84 mL) followed by LiHMDS (6.27 mL, 1.0 N in THF). The resulting mixture is stirred at RT for 3 min. The resulting mixture was partitioned between NH4Cl and EtOAc, the organic layer was separated, dried and concentrated to dryness. The residue was purified by FCC to provide the title compound (440 mg, 61%). MS (ESI): mass calcd. for C23H21F3N4O3, 458.16; m/z found, 459.1 [M+H]+.
