Two 14 C-isotopomers of duloxetine HCl (S-(+)-N-methyl-3(1-naphthalenyloxy)-3(2-thiophene)propanamine hydrochloride), a potent mixed serotonin/norepinephrine uptake inhibitor have been prepared by an asymmetric synthesis. The palladium catalyzed cross-coupling of 2-thienoyl chloride (3c) (or its [carbonyl- 14 C] isotopomer 3d) with vinyl tri-n-butyl-stannane, followed by addition of HCl afforded the
