Reaction Steps

Methyl 2-(2-chloro-4-methyl-6-p-tolylpyrimidin-5-yl)pentanoate (100 mg; 0.300 mmol), quinolin-5-ylboronic acid (156 mg; 0.901 mmol), tetrakis(triphenylphosphine) palladium(0) (34.7 mg; 0.030 mmol) were placed in a 5 mL reaction tube and dissolved in a mixture of degassed DME (1.50 mL) and water (0.5 mL). N,N-Diisopropylethylamine (0.185 mL; 1.202 mmol) was added, the tube was sealed and irradiated in a microwave oven at 130° C. for 1 h. The reaction mixture was partitioned between brine and dichloromethane, filtered over a phase separator filter (1PS) and concentrated under reduced pressure. The crude material was purified by flash chromatography on silica gel using a linear gradient of ethylacetate (10-80%) in heptane to give 84 mg (43%) of the title compound as a colorless oil.
