Reaction Steps
This compound was prepared according to general method E from methyl 2-(4-chloro-6-methyl-2-phenylpyrimidin-5-yl)pentanoate (0.08 g; 0.25 mmol), tetrakis(triphenylphosphine) palladium(0) (0.029 mg; 0.025 mmol), N,N-diisopropylethylamine (0.173 mL; 1 mmol) and 3,4-dihydro-2H-benzo[b][1,4]dioxepin-7-ylboronic acid (0.097 g; 0.5 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 0.092 g (75%) of the title compound.
