Versuchsvorschrift

To a solution of 2-[1-(3-chloro-2-pyridinyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl]-6-iodo-8-methyl-4H-3,1-benzoxazin-4-one (i.e. the benzoxazinone product of Example 1, Step D) (500 mg, 0.94 mmol) in tetrahydrofuran (15 mL) was added dropwise methylamine (2.0 M solution in THF, 1.4 mL, 2.8 mmol) and the reaction mixture was stirred for 3 hours, 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 400 mg of the title compound as a yellow solid.
