実験手順
N,N-Dimethyl-3-nitro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (356 mg, 1.22 mmol) was dissolved in 50 ml of ethyl acetate. This mixture was hydrogenated in an H-Cube® apparatus using 10% palladium on carbon as catalyst at 2-3 bar. The solvent was evaporated to give 324 mg (99% yield) of the title compound as a white solid. Purity 100%.
