Versuchsvorschrift

To ice-cooled carbon disulfide (77 ml) were added anhydrous aluminum chloride (61.2 g) and chloroacetyl chloride (36.5 g), and then 2,3-dihydro-3,3-dimethylindol-2-one (24.6 g) was added thereto. The mixture was stirred for 10 minutes at ambient temperature and for 4 hours at 35° to 40° C. The solvent was removed by decantation and to the residue was added ice-water. The resulting crystal was collected, washed with water and dried to give 5-chloroacetyl-2,3-dihydro-3,3-dimethylindol-2-one (37.39 g).
