2,4-Difluoronitrobenzene → 5-Fluoro-n-(2-methyl-1-phenylpropyl)-2-nitrobenzenamine

Participants

Reaction Steps

A solution of 2-methyl-1-phenylpropan-1-amine (1.0 g, 6.7 mmol), 2,4-difluoronitrobenzene (0.74 mL, 6.7 mmol) and N,N-diisopropylethylamine (2.3 mL, 13.4 mmol) in acetonitrile was stirred at room temperature for 32 h. The solvent was concentrated in vacuo, the residue was taken up in dichloromethane and washed with water, dried, and concentrated under reduced pressure to yield 1.79 g (93%) of the desired aniline: 1H NMR (400 MHz, CDCl3): δ 8.78 (br d, 1H), 8.21 (dd, 1H), 7.37-7.31 (m, 4H), 7.28-7.24 (m, 1H), 6.44-6.35 (m, 2H), 4.43 (t, 1H), 2.18 (m, 1H), 1.06 (d, 3H), 0.97 (d, 3H).
