Methylamine → Benzenamine, N-methyl-2-nitro-4-(trifluoromethyl)-

Participants

Reaction Steps

A stream of methylamine was bubbled through a solution of 1,3 g (6,2 mmol) 4-fluoro-3-nitrobenzotrifluoride in 25 ml dimethylformamide at 25° C. for 5 min. Stirring was continued at 25° C. for 2 h, and then the reaction mixture was evaporated in vacuo. The residue was stirred with water, and the precipitate was filtered off to give 1,17 g (86%) 4-methylamino3-nitrobenzotrifluoride. NMR (CDCl3): 8.4 (1H, s), 8.2 (1H, broad s), 7.6 (1H, dd), 6,9 (1H, d), 3.1 (3H, d).
