6-O-Methylerythromycin A (I) is protected with benzoic anhydride in the presence of triethylamine and DMAP in ethyl acetate to afford 2’,4”-di-O-benzoyl-6-O-methylerythromycin A (II). Treatment of the protected intermediate (II) with 1,8 diazabicyclo[5.4.0]undec-7-ene (DBU) followed by 1,1-carbonyldiimidazole (CDI) (III) in DMF yields 10,11-anhydro-2’,4”-di-O-benzoyl-12-O-imidazolylcarbonyl-6-Omethylerythromycin A (IV), which is converted to the 2’,4”-di-O-benzoyl-11-N-(4-azidobutyl)-6-O-methylerythromycin A 11,12-cyclic carbamate (V) by treatment with 4-azidobutylamine (XIII) and DBU in DMF. The cladinose sugar is cleaved from carbamate (V) by hydrolysis with 1 N HCl in acetone to provide 11-N-(4-azidobutyl)-5-(2’-benzoyldesosaminyl)-3-hydroxy-6-O-methylerythronolide A 11,12-cyclic carbamate (VI). 1-N-(4-Azidobutyl)-5-(2’-benzoyldesosaminyl)-3-oxo-6-O-methylerythronolide A 11,12-cyclic carbamate (VII) is prepared by oxidation of the secondary alcohol of intermediate (VI) with Dess-Martin periodinane (DMP).

Fluorination of the keto intermediate (VII) is accomplished with potassium tert-butoxide and N-fluo-robenzenesulfonamide (NFSI) in THF/CH2Cl2 at –20 °C to –15 °C to afford the fluoro-azide intermediate (VIII). The triazole intermediate (X) is prepared by a copper-catalyzed azide-alkyne cycloaddition reaction between the fluoro-azide intermediate (VIII) and 3-ethynylaniline (IX) in the presence of copper(I) iodide and DIEA in acetonitrile. Deprotection of the triazole intermediate (X) is accomplished by refluxing in methanol to yield solithromycin . 4-Azidobutylamine (XIII) is prepared by substitution of 1,4-dibromobutane (XI) with sodium azide in DMF/H2O at 80 °C to produce 1,4-diazidobutane (XII), which, without isolation, is subjected to partial reduction with triphenylphosphine in MTBE to afford 4-azidobutylamine (XIII) .
