Procedure
An acid chloride (0.4 g) prepared in the same manner as in Example 6 from 7-(2-chloro-4-trifluoromethylphenoxy)-2,4-dimethyl-3,4-dihydro-3-oxo-2H-1,4-benzoxazine-2-carboxylic acid (Compound 23) was dissolved in tetrahydrofuran (hereinafter abbreviated as THF) (5 ml), and the solution was stirred while blowing ammonia gas therein for one hour. Then, after an evaporation of the solvent, the residue was purified by silica gel chromatography (eluant: n-hexane/ethyl acetate=1/1) to give 0.3 g of the title compound (colorless crystals).
