Temperature: 105 °C

Procedure

A mixture of 8-bromo-2-(1-naphthyl)quinoline (2.03 g, 6 mmol), 2,6-diisopropylaniline (1.3 ml, 7 mmol), Pd(dba)2 (72 mg, 0.12 mmol), L=(N-[2′-(dicyclohexylphosphino)[1,1′-biphenyl]-2-yl]-N,N-dimethylamine (94 mg, 0.24 mmol), NadtBu (0.72 g, 7.2 mol) and toluene (15 mL) is stirred for 8 h under an argon atmosphere at 105° C. in an oil bath. The mixture is then poured into water and extracted with benzene (3×50 mL). The combined organic phase is washed with water and brine, and is then concentrated. The residue is purified by column chromatography (silica gel 40, hexane/toluene 2:1). Yield: 1.7 g (66%).
