1-[3-(acetylthio)-2-tert-butyloxycarbonylaminomethylpropanoyl]-L-proline tert-butyl ester (1.5 g) is dissolved in a mixture of anisole (6 ml) and trifluoroacetic acid (12 ml) and the solution is stored at room temperature for one hour. The solvent is removed in vacuo, the residue is distributed between water and ether. The aqueous phase is washed twice with ether and freeze-dried to yield 1-(3-acetylthio-2-aminomethylpropanoyl)-L-proline.
