Reaktionsschritte
200 ml of dichloromethane then 10 ml, i.e. 7.26 g (71.7 mmol) of triethylamine were added to 5 g (29.5 mmol) of 2-aminoindan hydrochloride. The mixture was stirred for 30 min, then 3.4 ml, i.e. 3.84 g (35.4 mmol) of ethyl chloroformate were added dropwise. The mixture was stirred for 30 min, then ice-water and an excess of 1N hydrochloric acid were 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. 4.25 g of amorphous solid were isolated.
