Reaktionsschritte
N-Boc-aminoacetonitrile (40.2 g, 257.4 mmol) and N-acetylcysteine (42.0 g, 257.4 mmol) were dissolved in methanol (300 mL) at 60° C. and ammonia was passed through for 18 h. The solvent was removed in vacuo. After ion exchange chromatography (Amberlite IRA-400 (AcOH)) and recrystallisation from acetone, 28.4 g (53%) of the sub-title compound was obtained as a white solid.
