Reaction Steps

1,1-Dimethylethyl 4-(4-fluoro-6-methyl-2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)-1-piperidinecarboxylate D4 (0.072 mmol, 25 mg) was dissolved in dichloromethane (5 ml) and was treated with HCl (3 ml of a 4M solution in 1,4-dioxane) at room temperature; the mixture was stirred at room temperature for two hours. Solvent was evaporated to afford the title compound, mono hydrochloride salt, M++H=250.
