Versuchsvorschrift

At room temperature, 1-chloro-4-isocyanato-2-(trifluoromethyl)benzene (656 mg, 2.96 mmol, 1.05 eq) was disolved in dichloromethane (5 mL). To the resulted solution, a solution of tert-butyl 4-(4-aminophenoxy)picolinate (805 mg, 2.81 mmol, 1 eq) in dichloromethane (5 mL) was slowly added dropwise. The mixture was stirred for 16 hours at room temperature. The solvent was removed under reduced pressure, and the resulted solid was purified by column chromatography (dichoromethane:methanol=30:1) to give the title compound (1.4 g, putity 95%, yield 85%) as a white solid.
