Reaktionsschritte

To a solution of 3-benzyloxyaniline (0.70 g, 3.51 mmol) in 1,2-dichloroethane (10 ml) were added 6-bromo-pyridine-2-carboxaldehyde (0.65 g, 3.51 mmol), sodium triacetoxyborohydride (1.49 g, 7.03 mmol) and acetic acid (0.80 ml, 14.1 mmol). The reaction mixture was shaken at 40° C. overnight. For work-up dichloromethane (100 ml) and 1 M sodium bicarbonate solution (40 ml) were added and the mixture was shaken. The organic layer was separated, dried over magnesium sulfate and evaporated. The residue was purified using flash chromatography (heptane/ethyl acetate=3:1) to yield an orange oil (1.03 g, 80%); MS (ISP): 371.1 ([81Br M+H]+), 369.1 ([79Br M+H]+).
