Procedure

1-(Benzo[d][1,3]dioxol-5-yl)-N-(3-bromo-4-(cyanomethyl)phenyl)cyclopropane-carboxamide (40 mg, 0.10 mmol), 4-(dimethylcarbamoyl)phenylboronic acid (29 mg, 0.15 mmol), 1 M K2CO3 (0.2 mL, 0.2 mmol), Pd-FibreCat 1007 (8 mg, 0.1 mmol), and N,N-dimethylformamide (1 mL) were combined. The mixture was irradiated in the microwave at 150° C. for 10 minutes. Volatiles were removed in vacuo and crude product was purified by chromatography on silica gel (eluting with 0-100% ethyl acetate in hexanes) to afford 5′-(1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-2′-(cyanomethyl)-N,N-dimethylbiphenyl-4-carboxamide (9.1 mg, 20%). ESI-MS m/z calc. 467.2, found 468.5 (M+1)+; retention time 2.96 minutes.
