By the reaction and treatment in the same manner as in Example 12 using 7-fluoro-1,2,3,4-tetrahydronaphthalene-1-carboxylic acid (0.41 g) and [(4-dimethylaminophenyl)methyl](4-methoxyphenyl)amine (0.54 g) as starting materials, N-[(4-dimethylaminophenyl)methyl]-7-fluoro-N-(4-methoxyphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide was obtained. This compound was dissolved in ethyl acetate, and 4 mol/L-HCl/dioxane was added. The precipitated solid was collected by filtration to give N-[(4-dimethylaminophenyl)methyl]-7-fluoro-N-(4-methoxyphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide hydrochloride ½ hydrate (0.52 g). melting point: 125.4° C.
