実験手順
2,3,4-Trifluoronitrobenzene (1.01 g) and pyruvic acid (0.75 g) were dissolved in methanol (8 ml). After adding 5% Pd—C (0.11 g), the mixture was stirred at 40° C. under a hydrogen gas pressure of 4.9 MPa (converted from 50 kgf/cm2) for 5 hours. After filtering off Pd—C, the obtained filtrate was concentrated under reduced pressure. Thus the title compound (1.20 g) was obtained as colorless crystals. Various spectral data of this product was identical with those of a specimen synthesized separately.
