反応手順
To N,N'-diacetyl-L-cystine (30.9 mmol, 10 g) dissolved in 20 mL of water was added ethylenediamine (61.8 mmol, 3.73 g) and ethanol (30 mL). The solution was concentrated to a thick paste which was redissolved in 80 mL of ethanol. Crystallisation occurred after 2 hours stirring at 10° C. Filtration and drying gave 6.2 g (45%) of the title compound.
