Participants

Reaction Steps

5.6 g (15 mmol) of the 5-{[(benzyloxy)carbonyl](4-methoxybenzyl)amino}valeric acid obtained in this way are dissolved in 60 ml of dichloromethane, and 2.2 ml of thionyl chloride are added. The mixture is heated under reflux for 30 min. It is then concentrated in vacuo, and the residue is again mixed with dichloromethane and concentrated once again. A viscous oil remains and is dried under high vacuum. 5.7 g (98% of theory) of the target compound are obtained and are reacted further without further purification and characterization.
