Reaction Steps
Methyl 2-(2-chloro-4-methyl-6-p-tolylpyrimidin-5-yl)pentanoate (100 mg; 0.300 mmol), p-toluenesulfonamide (0.061 mg; 0.361 mmol), palladium acetate (2 mg, 0.009 mmol) and xantphos (10 mg; 0.018 mmol) were placed in a 2 mL reaction tube and dissolved in dioxane (1 mL), the tube was purged with argon, sealed and irradiated in a microwave oven at 160° C. for 30 min. The reaction mixture was partitioned between a saturated sodium chloride solution 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 yield 32 mg (22%) of the title compound as a colorless oil.
