Procedure
4-Nitrophenyl chloroformate (7.0 g) was added to a dichloromethane (100 ml) solution of methyl 5-hydroxynicotinate (5.3 g) and diisopropylethylamine (6.1 ml), followed by stirring at room temperature for 1 hour. The reaction liquid was washed with water, and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the resulting solid was washed with EtOAc/hexane and dried under reduced pressure to obtain methyl 5-{[(4-nitrophenoxy)carbonyl]oxy}nicotinate (8.4 g).
