The condensation of dibenzocycloheptylidene derivative (I) with radiolabelled piperidine-3-carboxylic acid ethyl ester (II) by means of K2CO3 in ethyl acetate gives the adduct (III), which is hydrolyzed with aqueous HCl to yield the carboxylic acid (IV). Finally, this compound is submitted to optical resolution by means of chiral chromatography to provide the chiral radiolabelled compound.
