Reaction Steps
A solution of 1-fluoro-4-nitro-benzene (1 g, 7.1 mmol) and tert-butylamine (1.5 g, 21 mmol) in DMSO (5 mL) was stirred at 75° C. overnight. The mixture was poured into water (10 mL) and extracted with EtOAc (7 mL×3). The combined organic layers were washed with water, brine, dried over Na2SO4 and concentrated under vacuum to dryness. The residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate 30:1) to afford N-tert-butyl-4-nitroaniline (1 g, 73%). 1H NMR (CDCl3, 400 MHz) δ 8.03-8.00 (m, 2H), 6.61-6.57 (m, 2H), 4.67 (brs, 1H), 1.42 (s, 9H).
