Procedure

0.150 g of {[2-{2-(S)-[(1-Amino-isoquinolin-6-ylmethyl)-carbamoyl]-pyrrolidin-1-yl}-1-(R)-(4-methoxybenzyl)-2-oxo-ethyl]-tert.-butoxycarbonyl-amino}-acetic acid ethyl ester were treated with 5 mL of HCl in dioxane (5M solution) and the mixture was stirred for 3 h at ambient temperature. The solvent was distilled off and the remaining white solid was washed with diethyl ether and dried. Yield: 0.100 g (80%); (+)-APCI-MS: 534 (MH+).
