실험 절차
N,S-Diacetyl-DL-cysteinyl-L-proline (0.3 g) is dissolved in a mixture of water (4 ml) and concentrated ammonia (4 ml) under a blanket of argon. The solution is stored for 30 minutes at room temperature, saturated with sodium chloride and extracted with ethyl acetate and chloroform. The organic layers are pooled and concentrated to dryness in vacuo to obtain N-acetyl-DL-cysteinyl-L-proline, yield 0.1 g, Rf =0.25 (silica gel; benzene:acetic acid, 75:25).
