Abstract (en)
[origin: WO9928333A1] A process of preparing a 6-O-alkyl derivative of erythromycin C is provided. The process includes the steps of protecting the 2',4"- and 9-oxime hydroxyls with acetyl and ketal protecting groups, alkylating the 6-hydroxyl, removing the protecting groups and deoximating. Intermediates used in the process are also provided.
