実験手順

A solution of 1.18 g (4.92 mmol) of 1-bromo-2-(thiazol-2-yl)benzene and 1.67 g (6.55 mmol) of 4-metylphenyltrimethylstannane in 20 mL of dimethylformamide was treated with 621 mg of bis(triphenylphosphine)palladium(II) chloride. The reaction mixture was heated at 150° C. for 6 hours, cooled and poured into 300 mL of water. The resultant mixture was extracted with ether (3×100 mL). The combined ether extracts were washed with water (4×), dried over magnesium sulfate and evaporated under vacuum. The residue was purified by chromatography on silica gel, eluting with hexane/ether (100:10) to give 381 mg of the product. EI-MS: calculated for C16H13NS 251; found 250. 1H NMR (200 MHz, CDCl3): 2.36 (s, 3H), 7.14 (s, 4H), 7.24 (d, 1H), 7.40 (m, 1H), 7.42 (m, 2H), 7.73 (d, 1H), 8.20 (dt, 1H).
