Procedure

To a mixture of (2-hydroxy-ethyl)-(trans-4-methyl-cyclohexyl)-carbamic acid tert-butyl ester (0.75 g, 2.91 mmol) and 2-chlorobenzylbromide (0.90, 4.37 mmol) in DMF (8 mL) was added NaH (60% in mineral oil, 0.23 g, 5.83 mmol) and the reaction mixture was stirred for 16 h. H2O (4 mL) was added and the mixture was extracted with diethyl ether (3×5 mL). The organic phase was collected and the solvent was removed in vacuo to give the crude product of [2-(2-chloro-benzyloxy)-ethyl]-(4-methyl-cyclohexyl)-carbamic acid tert-butyl ester. This was dissolved in DCM (4 mL) and TFA (4 mL) was added and the mixture was stirred for 2 hs before the volatiles were removed in vacuo.
