Procedure

30 mg of N-tert-butoxycarbonyl-2(R)-methyl-4(S)-hydroxy-5(S)-amino-7(S)-isopropyl-8-(3-hydroxy-4-tert-butyl-phenyl)-octanoic acid (N-butyl)amide are treated with 0.6 ml of 4N hydrochloric acid in dioxane analogously to Example 1 and the product is purified by means of FC (15 g of silica gel, dichloromethane/methanol=9:1). The title compound is obtained: Rf (dichloromethane/methanol=9:1)=0.17; Rt (I)=28.54 minutes; FAB-MS (M+H)+ =435.
