Procedure

A solution of pyridin-4-ylmethanamine (505 uL, 5 mmol) and p-nitrophenyl chloroformate (1.0 g, 5 mmol) in dichloromethane (20 mL) was stirred at room temperature for 5 h. Upon completion, the product was collected by vacuum filtration, washed with dichloromethane and purified by preparative HPLC (10-90% acetonitrile in water) to provide 4-nitrophenyl pyridin-4-ylmethylcarbamate as a white solid. MS=274 (MH+).
