Reaction Steps
A mixture of 2-nitro-3-methylaniline (Newman, M. S.; Kannan R. J. Org. Chem., 1976, 41, 3356., 1.9 g, 12.4 mmol), 4-bromophenylethyl alcohol (2.5 g, 12.4 mmol), K2CO3 (1.7 g, 12.4 mmol) and CuI (230 mg, 1.24 mmol) was placed in a sealed tube and heated at 200° C. for 2 h. After cooling, the mixture was poured into water (100 mL) and extracted with ethyl acetate (300 mL). The organic layer was washed with 2N aqueous NaOH (100 mL) and brine (100 mL), then dried (Na2SO4), and concentrated. Purification by flash column chromatography on silica gel eluting with hexane/ethyl acetate (1:1) to afford 700 mg (21%) of the title compound as an orange oil: 1H-NMR (CDCl3) δ 7.77 (1H, br.s), 7.09–7.45 (6H, m), 6.69 (1H, d, J=6.3 Hz), 3.83 (2H, t, J=6.6 Hz), 2.82 (2H, t, J=6.6 Hz), 2.59 (3H, s).
