Participants

Reaction Steps

A mixture of cis and trans 4-(4-benzyloxy-phenyl)-cyclohexyl-amine (preparation see under example 43a, 1.25 g, 4.44 mmol), K2CO3 (1.23 g, 8.88 mmol), 1-(3-Bromo-propyl)-4-methyl-benzene (1.18 g, 4.44 mmol) and 2-butanone was stirred at 80° for 48 h. Water was then added and the products were extracted with EtOAc. The organic layer was dried (Na2SO4), evaporated and the residue was purified by chromatography (SiO2, CH2Cl2—MeOH—aq. NH3 140:10:1) to give cis-[4-(4-benzyloxy-phenyl)-cyclohexyl]-(3-p-tolyl-propyl)-amine (180 mg; 10 %) as a light yellow solid (MS: m/e=414.4 (M+H+))and trans-[4-(4-benzyloxy-phenyl)-cyclohexyl]-(3-p-tolyl-propyl)-amine (38 mg; 2%) as a light yellow solid (MS: m/e=414.4 (M+H+)).
