Reaction Steps

N-t-butyloxycarbonyl-L-phenylalanyl-L-proline benzylester (29.87 g, 66 mmole) was dissolved in 4.5N hydrochloric acid in dioxane solution (220 ml), and stirred for 1.5 hours at room temperature. The solvent was distilled off under reduced pressure, and gelatinous solid material thus obtained was dissolved in water (250 ml). The solution was washed with diethyl ether and the water layer was freeze-dried to obtain L-phenylalanyl-L-proline benzylester hydrochloride(yield: 26.53 g, 100%).
