Procedure
To a solution of 5-amino-2-chloropyridine (162 mg, 1262 μmol) and DIEA (275 μL, 1578 mmol) in DCM (6.0 mL) was added 4-nitrophenyl chloroformate (212 mg, 1052 μmol). The resulting mixture was then stirred at RT for overnight. A yellow precipitation was observed. The yellow solid was collected by filtration to give the title compound as a light yellow solid, which was used in the next step without purification requirement.
