実験手順

The 2-fluoro-4-trimethylsilylnitrobenzene (5.45 g, 25.6 mmol) was then dissolved in ethanol (100 mL), transferred to a Parr shaker bottle, flushed with nitrogen, then charged with 10% Pd—C (0.4 g). The reaction mixture was hydrogenated for 1 h on the Parr apparatus (45 psi H2), and then filtered through a plug of Celite. The filter cake was washed with ethanol, and the combined filtrates were concentrated. The resulting residue was purified by flash chromatography (250 mL silica gel, 95:5 hexane-ethyl ether), to afford the title compound as a tan oil (4.31 g, 92%).
