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-3-sulfonyl chloride (10. mg, 0.058 mmol, Maybridge, Cat. No. CC48303) and triethylamine (16 μL, 0.12 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=628.2.
