Versuchsvorschrift

To a suspension of NaHCO3 (504 g, 6.0 mol) and 2,3-dihydro-1H-indole (60 g, 0.5 mol) in CH2Cl2 (600 mL) cooled in an ice-water bath, was added dropwise acetyl chloride (78.5 g, 1.0 mol). The mixture was stirred at room temperature for 2 h. The solid was filtered off and the filtrate was concentrated to give 1-(2,3-dihydro-indol-1-yl)-ethanone (82 g, 100%).
