The resulting mixture was stirred 5 h at room temperature. A white precipitate was formed that was collected by filtration and washed with EtOAc. The solid was dried over night under high vacuum to yield trans-4-[2-(4-thieno[2,3-c]pyridin-7-yl-piperazin-1-yl)-ethyl]-cyclohexylamine trihydrochloride as a white solid (365 mg, 59%), MS (ISP) m/z=345.2 [(M+H)+].
