Reaction Steps

(3-Chloro-2-fluoro-phenyl)-(3H-imidazol-4-ylmethyl)-amine (0.24 g, 1 mmol) was dissolved in methanol (15 ml). Then acetaldehyde (0.28 ml, 5 mmol), zinc chloride (0.55 g, 4 mmol) and sodium cyanoborohydride (0.19 g, 3 mmol) were added and the reaction mixture was allowed to stir at 40° C. overnight. After cooling, the reaction mixture was poured onto ammoniumchloride/ice and extracted with ethyl acetate (2 times 50 ml). The organic layer was dried over magnesium sulfate and evaporated. The residue was purified using flash chromatography (SiO2; eluent: heptane/ethyl acetate=90:10) to yield a light yellow oil (0.16 g, 63%); MS (ISP): 254.1 ((M+H)+.).
