Procedure
By the reaction and treatment in the same manner as in Example 12 using 6-fluorochroman-4-carboxylic acid (0.29 g) and [(1-ethylpyrazol-4-yl)methyl](4-isopropylphenyl)amine (0.37 g) as starting materials, N-[(1-ethylpyrazol-4-yl)methyl]-6-fluoro-N-(4-isopropylphenyl)chroman-4-carboxamide (0.42 g) was obtained.
