Reaction Conditions

Reaction Steps

2-Amino-5-chloropyridine (1.05 g, 8.2 mmol) was suspended in 15 mL dry DCM under Ar, added dry pyridine (0.66 mL, 8.2 mmol), cooled to 0° C. and added 4-nitrophenol chloroformate. A white precipitate forms rapidly. Stirred at ambient temperature for 1 hour, filtered off solid, washed with water and then DCM. A white solid recovered which is consistent with title compound. (2.1 g, 88%) 1H-NMR (D6-DMSO)
