Reaction Steps
The coupling component of Example 25 was prepared by reaction of the sulphuric acid semi-ester (or its sodium salt) of N-ethyl-N-β-hydroxyethyl-aniline with sodium azide to form N-ethyl-N-β-azido-ethylaniline in a two-phase aqueous organic solvent system, for example in water/chlorobenzene, and reaction of the azido compound thus obtained with acetylene.
