4'-Fluoro-3'-nitroacetophenone → 3'-Amino-4'-fluoroacetophenone

Participants

Reaction Steps

A mixture of 1-(4-fluoro-3-nitrophenyl)-ethanone (4.94 g) and 5% Pt(S)/C (500 mg) in ethanol (50 mL) was hydrogenated at 50 psi for 3 hours. After filtration and concentration, the residue was purified by silica gel flash chromatography over silica gel (elution with 30% ethyl acetate in hexane) to give 3.3 g of the title compound as a solid.
