1-[2(S)-Hydroxy-3(S)-(N-(quinoline-2-carbonyl)-(L)-asparaginyl)amino-4-phenyl-butyl]-1-[cyclohexylmethyl]-2-[tert-butoxycarbonyl]-hydrazine → 1-[2(S)-Hydroxy-3(S)-(N-(quinoline-2-carbonyl)-(L)-asparagyl)amino-4-phenyl-butyl]-1-[cyclohexylmethyl]-hydrazine

Participants

Reaction Steps

Analogously to Example 98 (see below), 921 mg (1.39 mmol) of 1-[2(S)-hydroxy-3(S)-(N-(quinoline-2-carbonyl)-(L)-asparagyl) amino-4-phenyl-butyl]-1-[cyclohexylmethyl]-2-[tert-butoxy-carbonyl]-hydrazine (Example 100 A), see below) in 37 ml of formic acid are reacted to form the title compound and used directly in the next step.
