Versuchsvorschrift

N,N-Dimethylethylenediamine (178 μL, 1.54 mmol) was added to a solution of N-(5-chlorothiophen-2-ylmethoxy)phthalimide (220 mg, 0.75 mmol) in EtOH (5 mL), and the reaction allowed to stir at RT for 15 h Glacial acetic acid (1 mL) was then added to adjust the mixture to ca. pH 4 followed by a solution of N-(2-acetyl-4-chlorophenyl)trifluoromethanesulfonamide 19 (211 mg, 0.70 mmol) in EtOH (2 mL), and the mixture stirred for 15 h at RT. The reaction mixture was concentrated under vacuum, and the residue purified by column chromatography (eluting with CH2Cl2/PE, 1:1) to afford N-{4-chloro-2-[1-(5-chlorothiophen-2-ylmethoxyimino)ethyl]phenyl}trifluoromethanesulfonamide 194 (280 mg, 90%), as white crystals. 1H n.m.r.

N-(5-Chlorothiophen-2-ylmethoxy)phthalimide was prepared using the procedure reported in U.S. Pat. No. 4,071,533.
