実験手順

2-(2-Phenoxyphenyl)-2-methoxyiminoacetamide (3.77 g) was dissolved in pyridine (5.53 g). The solution was cooled to 0° C. Trifluoroacetic anhydride (4.40 g) was added dropwise. The mixture was stirred for 2 hours at 0° C., and then diluted with dil. hydrochloric acid and extracted with ethyl acetate. The extract was dried and concentrated to leave a residue, which was purified by column chromatography on silica gel to obtain 2-(2-phenoxyphenyl)-2-methoxyiminoacetonitrile (3.41 g).
