Paragraph 0027; 0053, (2018/10/10)
PROBLEM TO BE SOLVED: To provide a method of providing crystal of (S)-(+)-N-methyl-3-(1-naphthyloxy)-3-(2-thienyl)propylamine hydrochloride (general name:duloxetine hydrochloride) useful as an antidepressant with high purity and high bulk density. SOLUTION: There is provided a manufacturing method of duloxetine hydrochloride for depositing the duloxetine hydrochloride in a resulting mixture by mixing a solution by dissolving duloxetine hydrochloride into a solvent for dissolution containing at least one kind of polar solvent selected from water and alcohol having 1 to 3 carbon atoms with acetone, and setting a temperature when dissolving the duloxetine hydrochloride into the solvent for dissolution at 60°C or less.
