Procedure

An anhydrous toluene (30 mL) suspension of 1-nitro-5,6,7,8-tetrahydronaphthalen-2-yl triflate (1.95 g, 6.00 mmol), 3-aminobenzonitrile (1.06 g, 9.00 mmol), potassium carbonate (830 mg, 6.00 mmol), tetrakis(triphenylphosphine)palladium (346 mg, 0.30 mmol), and triphenylphosphine (158 mg, 0.60 mmol) was stirred at 110° C. for 18 hours. The reaction mixture was cooled on standing, and filtered. The filtrate was diluted with ethyl acetate. The obtained organic solution was washed with purified water, and dried over anhydrous sodium sulfate. The solvent was removed by evaporation under reduced pressure. The residue was purified by silica gel column chromatography (chloroform) to give the titled compound as orange powder (1.515 g, yield 86%).
