실험 절차

A solution of 1-[3-(tetrahydropyran-2-ylthio)-2-methylpropanoyl]-L-proline (1 g.) in a mixture of methanol (25 ml.) and concentrated hydrochloric acid (25 ml.) is stored at room temperature for 30 minutes. The solvents are removed in vacuo to yield 1-(3-mercapto-2-methylpropanoyl)-L-proline. Rf : 0.35 (silica gel, Benzene/acetic acid, 3:1), Rf 0.5 (silica gel, Methyl-ethylketone/acetic acid/pyridine/water 14:1:2:1) identical to the compound of Example 34.
