Reaction Steps
Ethyl N-(3-trifluoromethyl-2-pyridyloxy)-carbamate (2.30 g; 9.19 mmoles) was dissolved in 50 ml of toluene, and 2.34 g (27.6 mmoles) of n-propyl isocyanate and 0.2 g (2.0 mmoles) of triethylamine were added, and the mixture was stirred at 45° C. for 40 hours. The toluene and the excess of n-propyl isocyanate in the reaction mixture were evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate/hexane) to give 2.61 g (yield 85 %) of the desired compound as a colorless liquid.
