Preparation takes place in analogy to Example 81A from 105 mg (0.21 mmol) of benzyl[2-({(2S)-2,5-bis[(tert-butoxycarbonyl)amino]pentyl}amino)-2-oxoethyl]carbamate (Example 125A) in 50 ml of ethanol with the addition of 11 mg of palladium on activated carbon (10%). The product is reacted without further purification.
