Reaction Steps
This compound was prepared according to general method E from methyl 2-(4-chloro-6-methyl-2-phenylpyrimidin-5-yl)pentanoate (0.159 g; 0.5 mmol), tetrakis(triphenylphosphine) palladium(0) (0.058 mg; 0.05 mmol), N,N-diisopropylethylamine (0.345 mL; 2 mmol) and 2,3-dihydrobenzofuran-5-ylboronic acid (0.246 g; 1.5 mmol) in DME-water (2 mL) for 30 min. Purification by flash-chromatography on silica gel using a gradient of ethyl acetate (2-40%) in heptane furnished 0.184 g (91%) of the title compound.
