Reaction Steps

(3-Hydroxy-propyl)-(trans-4-methyl-cyclohexyl)-carbamic acid tert-butyl ester (1.5 g, 5.53 mmol) and phenol (0.52 g, 5.53 mmol) in dry THF (15 mL) was added DEAD (1.06 g, 6.08 mmol) and resin bound triphenyl phosphine (polystyrene, 2% cross linking, loading=3 mmol/g, 2.76 g). The reaction mixture was gently stirred for 18 h before the resin was filtered off and washed with THF (2×15 mL). The fitrate was concentrated in vacuo and the resulting residue was purified (SiO2, 0-20% EtOAc in heptane) to give 0.99 g of (4-methyl-cyclohexyl)-(3-phenoxy-propyl)-carbamic acid tert-butyl ester. This was dissolved in DCMTFA ((3:1), 16 mL) and the mixture was stirred for 18 h before the solvent was removed in vacuo to give 0.75 g of the TFA salt of (4-methyl-cyclohexyl)-(3-phenoxy-propyl)-amine.
