4-Bromo-3-methylaniline Chemical Properties,Usage,Production

Chemical Properties

grey to brownish crystalline powder

Uses

4-Bromo-3-methylaniline was used in the preparation of 1-(4-bromo-3-methylphenyl)pyrrolidin-2-one.

Synthesis

7149-70-4

6933-10-4

General procedure for the synthesis of 4-bromo-3-methylaniline from 2-bromo-5-nitrotoluene: First, N-(4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3-methylphenyl)methanesulfonamide (4-bromo-3-methylphenyl)amine was prepared. Subsequently, activated Raney nickel (0.4 g) was added to a suspension of 1-bromo-2-methyl-4-nitrobenzene (4 g, 18.51 mmol) in 200 mL of methanol. The mixture was stirred under hydrogen atmosphere (30 psi) for 3 hours. Upon completion of the reaction, the reaction mixture was filtered through Celite, the solvent was removed under reduced pressure and the residue was dried under vacuum to afford 4-bromo-3-methylaniline (3.4 g, 99% yield) as a white solid.1H-NMR data (CDCl3): δ 2.28 (s, 3H), 3.39 (brs, 2H), 6.38 (d, J = 8Hz, 1H), and 6.55 (s, 1H), 7.27 (d, J = 8Hz, 1H).
