To a solution of N-cyclopropyl-1-{4-[(ethylamino)carbonyl]-2-hydroxyphenyl}-5-methyl-1H-1,2,3-triazole-4-carboxamide (0.17 g) obtained in Example 141 in DMF (5 ml) were added 1-bromo-5-fluoropentane (0.11 g) and potassium carbonate (0.07 g), and the mixture was stirred at 50° C. overnight. The reaction mixture was allowed to cool to room temperature, water was added to the reaction mixture, and the mixture was extracted with ethyl acetate-hexane (2:1). The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column (ethyl acetate) to give the title compound as a pale-yellow amorphous substance (0.16 g, 77%).
