Procedure

1-(Benzo[d][1,3]dioxol-5-yl)-N-(4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)cyclopropanecarboxamide (42 mg, 0.10 mmol), 4-bromo-3-fluorobenzamide (24 mg, 0.11 mmol), Pd-FibreCat 1007 (10 mg), K2CO3 (1M, 240 mL), and DMF (1 mL) were combined in a scintillation vial and heated at 80° C. for 3 hr. The mixture was filtered and purified using reverse-phase preparative HPLC to provide 5′-(1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-2-fluoro-2′-methylbiphenyl-4-carboxamide (ESI-MS m/z calc. 428.5, found 429.5 (M+1); retention time 3.30 min).
