実験手順

A solution of N-(2-butyryl-4-chlorophenyl)trifluoromethanesulfonamide 29A (333 mg, 1.0 mmol), O-(4-chlorophenyl)hydroxylamine hydrochloride (200 mg, 1.10 mmol) and anhydrous NaOAc (91 mg, 1.10 mmol) in EtOH (30 mL) was stirred for 15 hours at RT. The reaction mixture was concentrated under vacuum, the residue filtered through a pad of silica (eluting with CH2Cl2/PE, 1:4) and the solvent removed under reduced pressure. The residue was purified by radial thin layer chromatography (eluting with CH2Cl2/PE, 1:19 to 3:7) to afford N-{4-chloro-2-[1-(4-chlorophenoxyimino)butyl]phenyl}trifluoromethanesulfonamide 166 (283 mg, 62%), as a yellow solid.
