실험 절차

A solution of 6-[(2-chloro-α,α,α,6-tetrafluoro-p-tolyl)oxy]-α-methyl-1H-benzotriazole-1-acetaldehyde oxime (5.0 g, 0.012 mol) in acetic anhydride is allowed to stand at 22° C. for 20 hours and concentrated in vacuo to give an oil residue. The residue is chromatographed on silica gel using chloroform as eluant to afford the title compound (I), 2.0 g, mp 118°-119° C., identified by elemental and NMR analyses and the title compound (II), 2.1 g, mp 95°-97° C., identified by elemental and NMR analyses.
