Reaction Steps

A 4M solution of hydrochloric acid in dioxane (10 ml) was added dropwise to a solution of 4-(4-chlorophenyl)-4-methylaminomethyl-piperidine-1-carboxylic acid tert-butyl ester (142 mg, 0.42 mmol) in methanol (10 ml). The reaction was stirred overnight at room temperature. After this period of time, the solvents were concentrated to give [4-(4-chlorophenyl)-piperidin-4-ylmethyl]-methylamine bis-hydrochloride (132 mg, 0.42 mmol, 100%). This compound was used in the subsequent step without further purification. LC-MS (LCT2) m/z 239 [M+H+], Rt 0.53 min.
