実験手順: A mixture of 4-isopropylbenzenethiol (2.288 g), 3-bromopyridin-2-amine (2.0 g), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.669 g), tris(dibenzylideneacetone)dipalladium(0) (0.529 g) and DIEA (7.47 mL) in toluene (57.8 mL) was stirred overnight under a nitrogen atmosphere at 120° C. The reaction mixture was added to water, filtered through celite, and the filtrate was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (2508 mg) as a pale-yellow solid. filtered through celite the filtrate was extracted with ethyl acetate The organic layer was washed with saturated brine dried over anhydrous magnesium sulfate concentrated under reduced pressure The residue was purified by silica gel column chromatography (ethyl acetate/hexane)

The exothermic reaction was allowed to cool down to room temperature. At 15° C. a solution of (4-bromomethyl-phenyl)-acetic acid (15.04 g, 65.68 mmol) in N,N-dimethylformamide (100 ml) was added. After stirring the reaction mixture at room temperature for 16 h the mixture was concentrated, diluted with water, and adjusted to pH=2 by adding HCl (2N). The aqueous phase was extracted three times with ethyl acetate. The combined organic layers were dried over MgSO4, filtered, and the solvent evaporated under reduced pressure to give the product as a yellow oil (19.5 g, 99%).
