NaH (150 mg, 3.80 mmol, 60%) was added to a solution of 6-bromo-pyridin-2-ylamine (300 mg, 1.73 mmol) in DMF at 0° C. followed by iodomethane (3.47 mL, 6.94 mmol). The reaction mixture was stirred for 1 hour at room temperature and was quenched with water. The aqueous phase was extracted with Et2O. The organic phase was washed with water, brine, dried over MgSO4, filtered and evaporated. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 95:5) to yield 90 mg (0.48 mmol, 28%) of (6-bromo-pyridin-2-yl)-methyl-amine.
