反応手順

A mixture of 4-methyl-2-nitroaniline (1.006 g, 6.612 mmol), 4-benzyloxybromobenzene (5.794 g, 22.02 mmol), cuprous iodide (62.9 mg, 0.3306 mmol), potassium carbonate (0.914 g, 6.612 mmol) and anhydrous o-xylene (18 mL) was heated at 150° for 24 hours. Added additional cuprous iodide (30 mg) and heated an additional 6 hours at 160°. The reaction was cooled to room temperature and the solvent removed by rotary evaporation under vacuum. The residue was purified by silica gel flash chromatography using 1:1 methylene chloride/hexanes as eluent to afford the title compound as a red oil which slowly crystallized (1.23 g, 56%).
