Versuchsvorschrift

N-(3-Cyano-4-neopentyloxyphenyl)-5-fluoro-2-methyl-1H-indole-3-carboxamide ¼ hydrate (0.8 g) obtained in Example 9,. potassium carbonate (0.2 g) and 2-bromoethyl acetate (0.4 g) were added to dimethylformamide (5 ml) and the mixture was stirred at 40° C. for 3 hr. Then the reaction mixture was treated with water and the oganic layer was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and the solvent was evaporated. The residue was separated and purified by silica gel column chromatography (mobile phase: chloroform) to give the title compound (0.3 g). melting point: 124-125° C.
