Procedure
By the reaction and treatment in the same manner as in Example 1 using 6-fluorochroman-4-carboxylic acid (1.96 g) and [(4-dimethylaminophenyl)methyl] (4-isopropylphenyl) amine (2.68 g) as starting materials, N-[(4-dimethylaminophenyl)methyl]-6-fluoro-N-(4-isopropylphenyl)chroman-4-carboxamide (2.89 g) was obtained. melting point: 95-98° C.
