反应详情

Platinum dioxide (1.0 g) was added to a solution of 2-fluoro-4-bromo-5-methoxycarbonyloxinitrobenzene (30.4 g, 0.1 mol) in ethanol (300 ml) and the solution was stirred in normal atmospheric pressure of hydrogen until absorption of hydrogen was terminated. After completion of the reaction, the catalyst was removed by filtration and the solvent was removed by distillation from the filtrate to give a brown solid (28.0 g) of 2-fluoro-4-bromo-5-methoxycarbonyloxianiline.
