N-t-butyloxycarbonyl-L-isoleucyl-L-proline benzylester (39.76 g, 95 mmole) was dissolved in 4N hydrochloric acid in dioxane (360 ml), and stirred for 30 minutes at room temperature. The solvent was distilled and the residue thus obtained was powdered in diethyl ether to obtain L-isoleucyl-L-proline benzylester hydrochloride(yield: 31.31 g, 92.9%).
