Participants

Reaction Steps

A solution of 3-amino-9-fluorenone (1.95 g, 10 mmols), triethylamine (2.07 ml, 15 mmols), in 25 ml of dried dichloromethane, is cooled to 10° C. and a solution of chloroacetyl chloride (1.18 g, 10.5 mmoles) in 10 ml of dried dichloromethane is then added drop by drop. The resulting mixture is kept stirring for 1 hour at room temperature overnight. The mixture is washed with 2×30 ml of water, dried over sodium sulfate and evaporated. 2.63 g 2-Chloro-N-(9-oxo-9H-fluoren-3-yl)-acetamide (97%) are obtained.
