Reaktionsschritte

92 mg (0.08 mmol) of tetrakis(triphenylphosphine)palladium are added to a suspension, kept under nitrogen, of 849 mg (4.0 mmol) of tripotassium phosphate, 344 mg (2.0 mmol) of 2-bromo-5-methylpyridine and 304 mg (2.0 mmol) of 3-hydroxymethylbenzeneboronic acid in 12 ml of dioxane and 1 ml of water, and the mixture is heated at the boil with stirring for 18 hours. The reaction mixture is cooled to room temperature and partitioned between water and ethyl acetate. The organic phase is dried over sodium sulfate, evaporated, and the residue is chromatographed on a silica-gel column with dichloromethane/methanol as eluent: [3-(5-methylpyridin-2-yl)phenyl]methanol as yellowish oil; LCMS 200.
