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 (42.1 mg, 0.100 mmol), 5-(3-bromophenyl)-tetrazole (22.5 mg, 0.100 mmol), a 1 M aqueous solution of potassium carbonate (0.50 mL), Pd-FibreCat 1007 (6 mg), and ethanol (0.50 mL) were combined. The mixture was heated at 110° C. for 5 min (5 min ramp time) in a microwave reactor. After cooling, the mixture was filtered and purified by prep-HPLC to provide 1-(benzo[d][1,3]dioxol-5-yl)-N-(6-methyl-3′-(2H-tetrazol-5-yl)-biphenyl-3-yl)cyclopropanecarboxamide. ESI-MS m/z calc. 439.2, found 440.2 (M+1)+; Retention time 2.59 minutes.
