Reaction Steps

A suspension of methyl 2-(4-chloro-6-methyl-2-(piperidin-1-yl)pyrimidin-5-yl)pentanoate (0.081 g; 0.25 mmol), tetrakis(triphenylphosphine) palladium(0) (0.029 g; 0.025 mmol), N,N-diisopropylethylamine (0.172 mL; 1.00 mmol) and 4-chloro-2-fluorophenylboronic acid (0.065 g; 0.375 mmol) in a mixture of DME-water (3:1, 1 mL) was heated at 100° C. for 2.5 h. The mixture was partitioned between brine and dichloromethane, filtered over a phase separator filter (1PS) and concentrated under reduced pressure. Purification by flash-chromatography on silica gel using a gradient of ethyl acetate (1-10%) in heptane furnished 0.049 g (38%) of the title compound as a colorless oil.
