A solution of 1-(1H-benzoimidazol-4-yl)ethanone (72 mg, 0.449 mmol), methylamine (2M in THF; 2.25 mL, 4.50 mmol) and HCl in 1,4-dioxane (4M; 0.337 mL, 1.35 mmol) in MeOH (2.7 mL) was stirred at room temperature for 3 days before it was cooled to 0° C. and NaBH4 (20 mg, 0.539 mmol) was added in a single portion. The mixture was stirred at room temperature overnight before it was diluted with MeOH, stirred for 1 hour and concentrated in vacuo. The residue was purified by SiO2 chromatography providing [1-(1H-benzoimidazol-4-yl)-ethyl]-methyl-amine (46 mg).
