Procedure: 20.5 g of 2-acetylaminoindan is added gradually into 200 ml of fuming nitric acid under cooling. After the reaction, the reaction mixture is poured onto 100 g of ice, and the solvent is evaporated from the chloroform extract, and the residue is recrystallized from isopropyl alcohol to give 18.6 g of 2-acetylamino-5-nitroindan. under cooling After the reaction the solvent is evaporated from the chloroform extract the residue is recrystallized from isopropyl alcohol

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of 2-aminoindan hydrochloride (10.40 g), potassium carbonate (34.2 g), water (100 ml) and ethyl acetate (150 ml) is added dropwise acetyl chloride (9.68 g) under ice cooling. The mixture is stirred at 0° C. for 1.5 hour, and the ethyl acetate layer is separated, washed with aqueous saline solution, dried, and then the solvent is distilled off under reduced pressure. The residue is recrystallized from ethyl acetate - n-hexane to give 2-acetylaminoindan (9.5 g) as colorless crystals. m.p. 126.5°-127.5° C. the ethyl acetate layer is separated washed with aqueous saline solution dried the solvent is distilled off under reduced pressure The residue is recrystallized from ethyl acetate - n-hexane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 2-aminoindan hydrochloride (13.3 g, 78 mmol), acetic anhydride (6 g, 0.157 mmol) and saturated sodium bicarbonate (100 mL) in ether (100 mL) was stirred at room temperature for 1 h. The organic phase was separated, and the aqueous layer back washed with ether. The combined organic layer was washed with saturated chloride solution, dried over magnesium sulfate, filtered and evaporated to give the acetamide (13.6 g) in quantitative yield. The organic phase was separated the aqueous layer back washed with ether The combined organic layer was washed with saturated chloride solution dried over magnesium sulfate filtered evaporated
