The acetylation of clarithromycin (I) with acetic anhydride gives the diacetate (II), which is acylated with CDI yielding the 12-O-(imidazolylcarbonyl) compound (III). The cyclization of (III) with ethylenediamine (IV) affords the cyclic carbamate (V), which is alkylated by reductocondensation with quinoline-3-carbaldehyde (VI) and NaBH(OAc)3 to give the secondary amine (VII). The methylation of this amine with formaldehyde and NaBH(OAc)3 yields the corresponding tertiary amine (VIII), which is treated with aqueous HCl to provide the descladinosyl compound (IX). Finally, this compound is acylated with 2-(2-pyridyl)acetic acid (X) by means of 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide (WSC) and deacetylated with methanol to afford the target compound.
