Reaction Steps
Acetonitrile (800 ml) is added to 2-aminoindan hydrochloride (50 g, 0.295 mole) followed by the addition of water (100 ml) and concentrated ammonium hydroxide (100 ml). To the resulting stirring solution tert-butyl bromoacetate (60 g, 0.308 mole) in acetonitrile (150 ml is added dropwise at room temperature and the resulting mixture stirred overnight at room temperature. The acetonitrile is evaporated on a rotary evaporator, water added to the residue and the product extracted several times into methylene chloride. The combined methylene chloride extract is washed twice with water, dried over magnesium sulfate, filtered and evaporated to afford the crude product as a tan oil. The crude product is purified further by silica-gel chromatography (chloroform). The desired fractions are concentrated and the hydrochloride prepared with ether-hydrochloric acid to afford tert-butyl N-(2,3-dihydro-1H-inden-2-yl)glycinate hydrochloride as a colorless solid (60 g, 72%); m.p. 175°; mass spectra (CI): 248(m+1, 100%).
