A synthesis of the (S)-enantiomer of the target compound has also been reported, starting from (S)-1-phenylethanolamine (XIV). Treatment with phenyl chloroformate (XV) and NaHCO3 yielded carbamate (XVI). Subsequent reaction of (XVI) with methanesulfonyl chloride and Et3N provided mesylate (XVII). The sulfonamide (XVIII) was prepared from sulfonyl chloride (VII) by treatment with ammonia gas in CH2Cl2. Condensation of this sulfonamide with mesylate (XVII) in the presence of NaH produced the chiral imidazolidinone (XIX). Finally, the target compound was obtained by condensation with 4-nitrobenzoyl chloride (XII), followed by reduction with H2 in the presence of Raney-Ni.

Protection of indoline (I) using trifluoroacetic anhydride provided N-trifluoroacetylindoline (II), which was sulfonated with chlorosulfonic acid to give sulfonyl chloride (III). Further treatment with ammonia in CH2Cl2 produced sulfonamide (IV). Phenylglycinol (V) was condensed with phenyl chloroformate to afford carbamate (VI). Subsequent reaction of (VI) with metanesulfonyl chloride and triethylamine yielded mesylate (VII). The condensation of sulfonamide (IV) with mesylate (VII), with concomitant cyclization of carbamate group and trifluoroacetyl deprotection, furnished imidazolone (VIII). This was further condensed with 4-nitrobenzoyl chloride (IX), and the resulting 4-nitrobenzamide (X) was finally reduced to the target aminobenzamide by hydrogenation over Raney Nickel.
