5-(1-(Benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-4′-(dimethylcarbamoyl) biphenyl-2-carboxylic acid (47 mg, 0.10 mmol) and 75 μL of a 2.0 M solution of methylamine in tetrahydrofuran (0.15 mmol) were dissolved in DMF (1.0 mL) containing Et3N (28 μL, 0.20 mmol). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (42 mg, 0.11 mmol) was added to the mixture and the resulting solution was allowed to stir for 3 hours. The mixture was filtered and purified by reverse phase HPLC to yield 5-(1-(benzo[d][1,3]dioxol-5-yl)cyclopropane-carboxamido)-N2,N4′,N4′-trimethylbiphenyl-2,4′-dicarboxamide (5.0 mg, 10%). ESI-MS m/z calc. 485.5, found 486.5 (M+1)4; retention time 2.54 minutes.
