Procedimiento

2,3,4-Trifluoronitrobenzene (3.54 g) and methyl pyruvate (2.32 g) were dissolved in ethanol (30 ml). After adding 5% Pd—C (2.0 g) and anhydrous magnesium sulfate (2.65 g), the mixture was stirred at 50° C. in a hydrogen atmosphere for 16 hours. After filtering off Pd—C and magnesium sulfate, the obtained filtrate was concentrated under reduced pressure. The residue thus obtained was subjected to silica gel column chromatography (ethyl acetate-normal hexane=1:4) to give the title compound (4.84 g) as a pale yellow oily substance.
