Vorschrift

1-(Benzo[d][1,3]dioxol-5-yl)-N-(3-bromo-4-(hydroxymethyl)-phenyl)cyclopropanecarboxamide (39 mg, 0.10 mmol), 4-(dimethylcarbamoyl)-phenylboronic acid (29 mg, 0.15 mmol), 1 M K2CO3 (0.3 mL, 0.3 mmol), Pd-FibreCat 1007 (8 mg, 0.1 mmol), and N,N-dimethylformamide (1 mL) were combined. The mixture was heated at 80° C. for 3 h. After cooling, the mixture was filtered and purified by reverse phase HPLC to yield 5′-(1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-2′-(hydroxymethyl)-N,N-dimethylbiphenyl-4-carboxamide (16 mg, 34%). ESI-MS m/z calc. 458.5, found 459.5 (M+1)+; Retention time 2.71 minutes.
