실험 절차
A solution of 3-chloro-5-(trifluoromethyl)picolinaldehyde oxime (1.0 eq.) and Burgess reagent (1.5 eq.) in tetrahydrofuran (0.5 M) was heated to 65° C. and stirred for 1 hour. The reaction was cooled to room temperature and diluted with ethyl acetate and water. The organic layer was washed with water, brine, dried over anhydrous MgSO4, and concentrated en vacuo to give a solid that was carried onto the next step without further purification.
