Versuchsvorschrift

4.0 M HCl in dioxane (8 ml) was added to a stirred solution (S)-2-({1-[(2R,5S)-5-((S)-2-tert-Butoxycarbonylamino-4-methyl-pentanoylamino)-2-methyl-6-hydroxy-azepan-1-yl]-methanoyl}-amino)-4-methyl-pentanoic acid methyl ester (490 mg, 0.93 mmol) in MeOH (8 ml). The reaction mixture was stirred for 2.5 h at RT, then was concentrated in vacuo by rotary evaporation and was used in the next reaction without further purification (430 mg).
