Alkylation of tert-butyl (5-hydroxy-2-naphthyl)propionate (I) with methyl bromoacetate (II) in the presence of K2CO3 provided ether (III). Subsequent deprotection of the tert-butyl ester of (III) using trifluoroacetic acid in CH2Cl2 gave carboxylic acid (IV). This was coupled to benzhydrylamine in the presence of EDC and DMAP to afford amide (VI). Finally, ester hydrolysis of (IV) with NaOH yielded the target compound.
