Reaction Steps

200 ml of dichloromethane, then 15 ml, i.e. 10.9 g (107.6 mmmol) of triethylamine were added to 5 g (29.5 mmol) of 2-aminoindan hydrochloride. The mixture was stirred, then 2.6 ml (29.5 mmol) of propionyl chloride were added and stirring was continued at room temperature for 12 h. Dilute hydrochloric acid was added, the precipitate was filtered, washed, dried and purified by chromatography on a silica gel column, eluted with an 80:20 mixture of dichloromethane/ethyl acetate. 4.87 g of beige solid were isolated.
