To a solution of (5-bromopyridin-2-yl)methanamine (500 mg, 2.67 mmol) in DCM (10 mL) was added Et3N (405 mg, 4.0 mmol) and AcCl (250 mg, 3.18 mmol) at 0° C. The mixture was then warmed to room temperature for 2 h when the reaction was quenched with water and extracted with DCM. The organic layer was concentrated to give the crude product which was used in next step without further purification. (540 mg, Yield 90%). LCMS (m/z): 229.0 (M+1).
