Reaction Steps

To a solution of 5-cyclopropyl-pyridin-2-ylamine (1.1 g, 8.19 mmol) in dry chloroform (100 mL) was added bromine (0.42 mL, 8.2 mmol) in chloroform (11 mL) at room temperature and stirred for 18 hours. An aqueous solution of sodium thiosulfate was added, the aqueous phase was extracted with dichloromethane, the combined organic phases were dried over sodium sulfate, the solvent was evaporated and the residue purified by silica gel chromatography using ethyl acetate/hexane as eluent. The title compound was obtained as light yellow oil (1.0 g, 57%).
