Procedure

1-(2-Benzoylthioacetyl)-L-proline obtained in Example 1, is dissolved in methanol and an ethereal solution of diazomethane is added until there is a persistent yellow color. After 15 minutes, a few drops of acetic acid are added and the solvent is removed in vacuo to obtain 1-(2-benzoylthioacetyl)-L-proline methyl ester.

Workup

  1. customthe solvent is removed in vacuo
