Reaction Steps

A vigorously stirred solution of 13.25 g (66 mmol) of 2'-bromoacetophenone and 22.8 g (89 mmol) of 4-methylphenyl-trimethylstannane in 190 mL of dimethylformamide under a nitrogen atmosphere was treated with 8.64 g (12 mmol) of bis(triphenylphosphine)palladium(II) chloride and the resulting mixture heated at 150° C. for 6 hours. The reaction mixture was cooled, poured into water (1000 mL) and the resultant suspension extracted with ethyl ether. The combined extracts were washed with water (4×), dried over magnesium sulfate and evaporated under vacuum. The residue was purified by preparative high pressure liquid chromatography on silica gel, eluting with hexane/ethyl acetate (10:1) to give 9.8 g (47 mmol, 71%) of product as an oil. El-MS: calculated for C15H14O 210: found 210 (M+). 1H NMR (200 MHz, CDCl3): δ 1.98 (s, 3H), 2.37 (s, 3H), 7.20 (s, 4H), 7.3-7.5 (m, 4H).
