7-Fluoro-1,2,3,4-tetrahydronaphthalene-1-carboxylic acid → N-[(4-dimethylaminophenyl)methyl]-7-fluoro-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide

Participants

Reaction Steps

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-isopropylphenyl)amine (0.57 g) as starting materials, N-[(4-dimethylaminophenyl)methyl]-7-fluoro-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide (0.85 g) 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-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide hydrochloride (0.85 g). melting point: 165.6° C.
