The copper-catalyzed “click” reaction of an azide with an alkyne has become a popular method to build up 1,4-substituted 1H-1,2,3-triazoles in medicinal chemistry and this approach was used on a laboratory scale during the preparation of novel macrolide 1. However, the manufacture of the key azide component, as well as its subsequent use in the presence of a copper catalyst on a large scale, was associated
