Versuchsvorschrift
To a solution of [3-(2-Hydroxy-ethylamino)-propyl]-carbamic acid tert-butyl ester (900 mg, 4.1 mmol) in THF (20 mL) was added a 1M solution of BH3 in THF. The mixture was refluxed for 24 hours under nitrogen. The reaction was allowed to cool down and water (5 mL) was carefully added with vigorous stirring. The reaction mixture was concentrated to low volume and treated with a 6M aqueous solution of HCl (60 mL). The mixture was refluxed for 24 h. The mixture was concentrated to dryness then co-evaporated several time with methanol to give the desired 2-(3-methylamino-propylamino)-ethanol (399 mg, 2.46 mmol)
