  • (E)-3-(4-bromobut-2-en-1-yl)-6-chloropyrido[3,4-d]pyrimidin-4(3H)-one [ No CAS ]
YieldReaction ConditionsOperation in experiment
71% General procedure: A mixture of K2CO3 (267mg, 1.94mmol) and 1 (250mg, 0.969mmol) in anhydrous DMF (5.0mL) was stirred at room temperature for 30min. To this white suspension was added 2a (392mg, 1.94mmol), and the resulting reaction mixture was stirred at room temperature for 2h. The resulting mixture was quenched with water, and the aqueous solution was extracted with EtOAc (3×10.0mL). The combined organic layers were washed with brine (3×10.0mL), dried with anhydrous Na2SO4, filtered, and concentrated under vacuum to give the crude product. The crude product was purified by flash silica gel column chromatography (hexane/CH2Cl2=1/2) to afford 3a as white crystals (276mg, 75%).
