Procedure

A solution of tert-butyl {1-[2-(3,4-dichlorophenyl)-2-(1-hydroxycyclohexyl)ethyl]piperidin-4-yl}carbamate (130 mg, 0.28 mmol) (Example 13), in diethyl ether (2 mL) was treated with a 4 N solution of hydrogen chloride in dioxane (1 mL). The resulting solution was stored at 25° C. for 16 h, during which time crystals began to form. The mixture was transferred to the refrigerator where it was stored for an additional 16 h. The resulting crystals were collected, washed with diethyl ether, and dried in vacuo to yield 101 mg (82%) 1-[2-(4-aminopiperidin-1-yl)-1-(3,4-dichlorophenyl)ethyl]cyclohexanol dihydrochloride as a white solid. MS m/z 371/373/375 ([M+H]+); HRMS: calcd for C19H28Cl2N2O.2.00 HCl, 442.1112; found (ESI), 371.1642.
