11 ml of a 4M solution of hydrogen chloride in dioxane are added to a solution of 160 mg (0.267 mmol) of benzyl{(1S)-5-{[(benzyloxy)carbonyl]amino}-1-[2-({3-[(tert-butoxycarbonyl)amino]-2-hydroxypropyl}amino)-2-oxoethyl]pentyl}carbamate (Example 160A) in 5.5 ml of dioxane at 0° C. The mixture is stirred at RT for 1 h. The reaction solution is concentrated, coevaporated with dichloromethane several times and dried under high vacuum. The crude product is reacted without further purification.
