To a solution of tert-butyl (2-(5-chloropyridin-3-yl)ethyl)carbamate (93 mg, 0.36 mmol) in DCM (4 mL) was added 3-chloroperbenzoic acid (85%, 94.8 mg, 0.54 mmol) at 0° C. The resulting reaction mixture was stirred at room temperature for 1.5 h. The reaction was quenched with aqueous solution of sodium thiosulfate and extracted with DCM. The combined organic layers were washed with aqueous solution of potassium carbonate and brine, dried over sodium sulfate and concentrate to give a crude product, which was used directly in the next step without further purification (90 mg, crude). MS (ESI) m/z 273.1 [M+H]+.
