N-t-butyloxycarbonylglycyl-L-proline benzylester (18.12 g, 50 mmole) was dissolved in 4N hydrochloric acid in dioxane (220 ml) solution, and stirred for 20 minutes at room temperature. The solvent was distilled off and the residue thus obtained was powdered in diethyl ether to obtain glycyl-L-proline benzylester hydrochloride (yield: 13.21 g; 88.4%).
