[CH:1]1([C:6]([CH:8]([NH:13]C(=O)OC(C)(C)C)[CH:9]([CH3:12])[CH2:10][CH3:11])=[O:7])[CH2:5][CH2:4][CH2:3][CH2:2]1.[ClH:21]>>[Cl-:21].[CH:1]1([C:6](=[O:7])[CH:8]([NH3+:13])[CH:9]([CH3:12])[CH2:10][CH3:11])[CH2:5][CH2:4][CH2:3][CH2:2]14 (0.18 g, 0.63 mmol) was dissolved in 2 ml HCl (7 N in dioxane). After completion of the reaction the solvent was removed and the resulting oil was purified by column chromatography on silical gel using a chloroform/methanol/water gradient.
