実験手順
N-triphenylmethyl-2-paranitrophenoxycabonylthioethylamine (300 mg) and L-proline (356 mg) were subjected to similar reactions to those described in References 2 and 4 to give 2-((S)-2-carboxypyrrolidino)carbonylthioethylamine (crude formate: 216 mg). The product was dissolved in anhydrous methanol (5 ml). Triethylamine (573 μl) and mitomycin A (287 mg: 1.0 molar equivalent) were added to the reaction solution which was then treated in a similar manner to that described in Example 1 to obtain Compound 31 (112 mg) in the form of grayish blue powders with a yield of 51%.
