To a solution of 4-{1-[3-({[(2,2,2-trifluoroethyl)amino]carbonyl}amino)phenyl]-1H-benzimidazol-5-yl}benzoic acid (20.0 mg, 0.0440 mmol) and cyclopropylmethylamine (6.3 mg, 0.088 mmol, Aldrich, Cat. No. 359521) in N,N-dimethylformamide (1 mL) was added benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (23 mg, 0.053 mmol, Adv. ChemTech. Cat. No. RC8105) and N,N-diisopropylethylamine (23 μL, 0.13 mmol). The reaction mixture was stirred at r.t. for 2 h, then diluted with MeOH, and purified by RP-HPLC (pH=10) to afford the desired compound. LCMS (M+H)+: m/z=508.2.
