By the reaction and treatment in the same manner as in Example 106 using N-[(4-dimethylaminophenyl)methyl]-5-hydroxy-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide (0.66 g) and 2-chloro-N,N-dimethylethylamine hydrochloride (0.32 g) as starting materials, 5-[2-(dimethylamino)ethoxy]-N-[(4-dimethylaminophenyl)methyl]-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide (0.54 g) was obtained. This compound was dissolved in ethyl acetate, and oxalic acid was added. The precipitated solid was subjected to recrystallization from ethyl acetate to give 5-[2-(dimethylamino)ethoxy]-N-[(4-dimethylaminophenyl)methyl]-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide oxalate ¼ hydrate (93.8 mg).
