Reaction Steps

To a solution of tert-butyl 4-(4-{1-[3-({[(2,2,2-trifluoroethyl)amino]carbonyl}amino)phenyl]-1H-benzimidazol-5-yl}-1H-pyrazol-1-yl)piperidine-1-carboxylate (130 mg, 0.22 mmol) in ethyl acetate (2 mL) was added 4.0 M hydrogen chloride in dioxane (0.22 mL, 0.89 mmol). The suspension was stirred at r.t. 2 h. and then concentrated under reduced pressure to afford the desired compound as HCl salt. LCMS (M+H)+: m/z=484.2.
