The racemic form of E-5880 is prepared as follows: The esterification of 2-methoxy-1,3-propanediol (I) with phenyl chlorocarbonate (II) in pyridine gives the diester (III), which is treated with 2-(aminomethyl)pyridine (IV) in refluxing chloroform, yielding the carbamate (V). The reaction of (V) with 4-hydroxypiperidine (VI) in refluxing chloroform affords the dicarbamate (VII), which by treatment with octadecyl isocyanate (VIII) gives the tricarbamate (X). Alternatively, (X) can be obtained by treatment of (VIII) with carbonate (II), yielding the intermediate (IX), which by treatment with octadecylamine (XI) at 100 C affords (X). The acylation of (X) with 2-methoxybenzoyl chloride (XII) in pyridine gives the precursor (XIII), which is finally treated with ethyl iodide in excess at reflux temperature and submitted to an ion exchange resin (Amberlite IRA-410 Cl- type). The optically active (R)-enantiomer is synthesized starting from L-mannitol.
