A solution of 219 mg (0.524 mmol) of trans-Methanesulfonic acid 4-{4-[(4-chloro-phenoxycarbonyl)-methyl-amino]-cyclohexyl}-butyl ester and 0.48 ml of N-allyl methyl-amine in 1 ml of MeOH was stirred over night at RT, and for 2 h under reflux. After concentration of the reaction-mixture in vacuo, the crude product was purified by chromatography over silica gel with EtOAc/H2O/AcOH/Aceton (6:2:1:1) to give 165 mg (80%) of clean trans-{4-[4-(Allyl-methyl-amino)-butyl]-cyclohexyl}-methyl-carbamic acid 4-chloro-phenyl ester, MS: 393 (MH+, 1Cl).
