Reaction Steps

A mixture of 5-bromo-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-nitro-1H-pyrazole-3-carbonitrile (EP 295118 A1, 50 mg, 0.12 mmol) and methylamine (2M in tetrahydrofuran, 1.0 mmol, 2.0 mmol) was heated at 55° C. for 2.5 h. To the reaction mixture was added water (5 ml), followed by ethyl acetate (5 ml). The two layers were separated and the aqueous layer was extracted with ethyl acetate (3×5 ml). The combined organic phases were dried (MgSO4) and concentrated in vacuo to give the titled compound (42 mg).
