Reaction Steps

To a solution of N-{3-[5-(1-piperidin-4-yl-1H-pyrazol-4-yl)-1H-benzimidazol-1-yl]phenyl}-N′-(2,2,2-trifluoroethyl)urea HCl salt (20.0 mg, 0.0385 mmol) in acetonitrile (1 mL) was added 1-methyl-1H-pyrazole-4-carbonyl chloride (8.3 mg, 0.058 mmol, Matrix Sci., Cat. No. 019861) and pyridine (60 μL, 0.8 mmol), the solution was stirred at r.t. overnight. The reaction solution was diluted with MeOH and then purified by RP-HPLC (pH=10) to afford the desired compound. LCMS (M+H)+: m/z=592.3.
