Procedure

1,1-Dimethylethyl 4-(6-chloro-4-fluoro-2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)-1-piperidinecarboxylate (D8) (0.203 mmol, 75 mg) and HCl (233 microliters of a 4M solution in 1,4-dioxane) were mixed together and stirred at room temperature for two hours. Solvent was evaporated to afford the title compound, mono hydrochloride salt, complete conversion, M++H=270.
