Versuchsvorschrift

Triethylamine (3.48 mL, 25.0 mmol) was added to a solution of isoindoline (4.98 g, 25.0 mmol) in chloroform (100 mL) at room temperature and the mixture was cooled in ice. Trichloroacetic acid chloride (2.79 mL, 25.0 mmol) was added dropwise thereto and the reaction mixture was warmed to room temperature and stirred for 1 hr. The reaction mixture was concentrated under reduced pressure and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1) to afford 2,2,2-trichloro-1-(1,3-dihydro-2 H-isoindol-2-yl)ethanone as a purple powder (6.59 g).
