Reaction Steps

To 3-(4-bromo-phenyl)-1-(2-methyl-pyridin-4-yl)-3-o-tolyl-propan-1-one ((example 74, step 5), 300 mg) in DMF (3 mL) tetrakis(triphenylphosphine)palladium (130 mg), methyl acrylate (0.103 mL) and triethylamine (0.16 mL) were added. The reaction mixture was stirred at 100° C. overnight, was cooled to room temperature and diluted with EtOAc and a saturated solution of ammonium chloride. The phases were separated and the inorganic one extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by flash chromatography on silica gel (EtOAc/n-heptane 1:1) to yield the title compound (62 mg, 20%) as a yellow oil, MS (ESI+): m/z=400.1912 ([M+H]+).
