実験手順

To a solution of 2-[3-chloro-1-(3-chloro-2-pyridinyl)-1H-pyrazol-5-yl]-6-cyano-8-methyl-4H-3,1-benzoxazin-4-one (i.e. the cyano-benzoxazinone product of Example 3, Step F) (100 mg, 0.25 mmol) in tetrahydrofuran (5 mL) was added dropwise ammonium hydroxide (0.5 mL, 12.8 mmol) at room temperature. The reaction mixture was then stirred for five minutes, at which point thin layer chromatography on silica gel confirmed completion of the reaction. The tetrahydrofuran solvent was evaporated under reduced pressure, and the residual solid was purified by chromatography on silica gel to afford 55 mg of the title compound, a compound of the present invention, as a white solid that decomposes in the melting apparatus above 255° C.
