Procedimiento

A solution of N-[2,6-diethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethylethyl)phenyl]-3-nitro-4-(1,2,4-triazol-1-yl)benzamide (473 mg, 0.89 mmol) (Example I2) in ethanol (9 ml) was charged with palladium on carbon (10%) (140 mg, 0.13 mmol) and was stirred under a atmosphere of hydrogen for 15 hours. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by column chromatography on silica gel (eluent: cyclohexane/ethyl acetate 1:4) to give Compound No. B2 of Table B (328 mg, 74% yield) and Compound No. C1 of Table C (18 mg, 4% yield).
