reduction of the azide and subsequent methylation of the resulting amine in one pot. A similar reaction, with ethanol as the solvent, gave the N-ethyl derivative. The 2-amino analogues were finally obtained by the reduction of the azide function using triphenylphosphine. Acylation of the amine using acetic, propionic, or valeric anhydride afforded the corresponding 2-amido derivatives. Deprotection of
