6.98 g (22.43 mmol) of tert-butyl 1-[3-(benzylamino)benzyl]cyclopropanecarboxylate were dissolved in 50 ml of ethanol and 50 ml THF, and 0.48 g (0.45 mmol) of palladium (10% on carbon) were added. At RT, the mixture was stirred under a hydrogen atmosphere at atmospheric pressure for 2 h. The reaction mixture was then filtered off with suction through kieselguhr, the residue was washed with THF and the filtrate was concentrated. The crude product was purified by chromatography on silica gel (mobile phase cyclohexane/ethyl acetate 10:1). This gave 3.66 g (65.9% of theory) of the title compound.
