Oxime product is isolated from reaction mixture by extraction with chlorinated hydrocarbon at pH 9-11 and subjected to Beckmann rearrangement by agency of arenesulfonic acid chloride in two-phase water-chlorinated hydrocarbon system to form erythromycin imino-ester. The latter is isolated by crystallization at pH 9-11 and temperature 60+-5 C and reduced in aqueous medium at room temperature with 0 to 0.2 molar excess of complex metal borohydride to give azaerythromycin. The latter is methylated, in the form of borate complex with mineral or organic acid (preferably, hydroxyacid), at pH 2.5, with formaldehyde in chloroform in presence of formic acid. Methylation product is isolated by reextraction with water at pH 4.5-5.5.
