Protection of 2'-O-acetyl-6-O-methylerythromycin A (I) with chlorotrimethylsilane afforded the 4''-O-trimethylsilyl derivative (II). Subsequent treatment with carbonyldiimidazole and NaH produced the dehydrated imidazolide (III), which was converted to the cyclic carbamate (V) upon reaction with 4-chlorophenethyl amine (IV). Acid hydrolysis of the cladinose moiety gave alcohol (VI), and further condensation with carbonyldiimidazole yielded imidazolide (VII).
