该中间体在本合成路线中的序号：(V)The acylation of 5-(benzyloxy)indole (I) with ethyl chloroformate produced the N-(ethoxycarbonyl)indole (II), which was debenzylated by transfer hydrogenolysis with ammonium formate in the presence of Pd/C to afford the 5-hydroxyindole (III). Condensation of (III) with 3-chloro-4-fluorobenzonitrile (IV) produced the diaryl ether (V). Then, basic hydrolysis of the cyano and ethoxycarbonyl groups of (V) gave the benzoic acid derivative (VI). Finally, N-alkylation of the indole ring of (VI) with 4-phenoxybenzyl bromide (VII) furnished the title compound.
