The synthesis of [14C]-labeled Bay-u-3405 by two closely related ways has been described: 1) [14C]-Labeled aniline (I) is diazotized and reduced with sodium sulfite, yielding the labeled hydrazine (II), which is condensed with the monoketal of cyclohexane-1,4-dione (III) under Fisher's indole synthesis (ZnCl2) to afford the tetrahydrocarbazole (IV). The hydrolysis of (IV) with HCl in THF/water yields 1,2,3,4-tetrahydrocarbazol-3-one (V), which is submitted to a reductive condensation with (S)-1-phenylethylamine (VI) by means of tetrabutylammonium borohydride, yielding preferentially the secondary amine (VII), which, after purification, is dealkylated with ammonium formate and Pd/C to afford 1,2,3,4-tetrahydrocarbazole-3(R)-amine (VIII). The acylation of (VIII) with 4-fluorophenylsulfonyl chloride (IX) gives the corresponding sulfonamide (X), which is condensed with acrylonitrile by means of NaH, yielding 3-[3(R)-(4-fluorophenylsulfonamido)-1,2,3,4-tetrahydrocarbazol-9-yl]pro pionitrile (XI). Finally, this compound is hydrolyzed in the usual way. 2) The condensation of the sulfonamide (X) with methyl acrylate by means of NaH as before gives 3-[3(R)-(4-fluorophenylsulfonamido)-1,2,3,4-tetrahydrocarbazol-9-yl]propionic acid methyl ester (XII), which is finally hydrolyzed in the usual way.
