The present disclosure provides solution to the problem associated in the preparation of duloxetine hydrochloride. This disclosure is successful in preventing the racemization and thereby prevents the formation of unwanted isomer of duloxetine hydrochloride. In addition, the disclosure provides a simple technique for removal of unreacted reactant, 1-fluoronapthalene used as a reactant in the process to obtain (S)-(+)-N-methyl-3(1-naphthalenyloxy)-3-(2-thienyl)propanamine hydrochloride, compound of formula (VI).
