Reaction Conditions:
with hydrogen;palladium 10% on activated carbon in methanol; under 2585.81 Torr; for 3 h;
Steps:
10.1
4,5-Difluoro-2-nitro-aniline (10 g, 57 mmol) and 10% palladium on carbon (2.0 g, 1.9 mmol) were placed in methanol (150 mL). The mixture was hydrogenated at 50 psi in a hydrogenator. After 3 hours the reaction mixture was filtered through diatomaceous earth and concentrated to a solid which was dried overnight (8.05 g, 98%).
