2-Fluoro-5-methoxycarbonyloxy-4-methylnitrobenzene → 5-Amino-4-fluoro-2-methylphenyl Methoxyformate

Participants

Reaction Steps

A solution of (4-fluoro-2-methyl-5-nitrophenyl) methyl carbonate (3 g, 13 mmol), (prepared as described in EP 0307777 A2), in ethanol (60 ml) containing platinum(IV)oxide (300 mg) was stirred under hydrogen at 0.3 atmosphere for 1 hour. After filtration and evaporation of the solvent, 2-fluoro-5-methoxycarbonyloxy-4-methylaniline was isolated as a solid (2.6 g, 100%). 1H NMR Spectrum: (CDCl3) 2.07(s, 3H); 3.87(s, 3H); 6.52(d, 1H); 6.80(d, 1H)
