Participants

Reaction Steps

(21 mmol) of methyl(S)-2-(4-benzylpiperazin-1-yl)-3-tert-butoxycarbonylaminopropanoate (prepared as described in example 17.4) in 120 ml of ethanol, degassed beforehand under a nitrogen stream. The reaction medium is then placed under a hydrogen atmospheric pressure for 24 h and then filtered through celite and thoroughly rinsed with dichloromethane. After concentration under vacuum, 6.1 g (100%) of methyl (S)-3-tert-butoxycarbonylamino-2-piperazin-1-ylpropanoate are obtained.
