Procedure

A mixture of 4-(3-phenyl-propylamino)-cyclohexanone (1.9 g, 8.21 mmol), K2CO3 (1.15 g, 8.3 mmol), benzyl chloroformate (1.42 g, 8.3 mmol) and CH2Cl2 (20 ml) was stirred at r.t for 1.5 h. H2O (50 ml) was added, and the mixture was extracted with CH2Cl2. The organic layer was dried (Na2SO4), evaporated and the residue was purified by chromatography (SiO2, CH2Cl2—MeOH 95:5) to give (4-Oxo-cyclohexyl)-(3-phenyl-propyl)-carbamic acid benzyl ester as a yellow oil (2.7 g, 90%, MS: m/e=365(M+)).
