Procedure
Pyridine (2.9 mL) was added to a solution of 2-trifluoromethyl-5-aminopyridine (1.95 g) in chloroform (15 mL), the mixture was cooled in ice, and phenyl chloroformate (1.8 mL) was added thereto. The resulting mixture was stirred at room temperature overnight, and the reaction mixture was concentrated under reduced pressure. The residue was washed with isopropyl ether to afford phenyl[6-(trifluoromethyl)pyridin-3-yl]carbamate (2.16 g).
