ABSTRACT:
Vindesine is prepared by converting 4-desacetyl VLB C-3 carboxhydrazide to the corresponding azide with a nitrite such as n-butyl nitrite in THF and then reacting the thus formed azide with triphenylphosphine to yield an intermediate acyl iminophosphorane, which compound is decomposed with acid to yield vindesine of high purity and in good yield.
