Reaction Conditions

Reaction Steps

A mixture of 6-chloro-4-aminopyrimidine (2.00 g, 15.4 mmol), palladium acetate (361 mg, 1.61 mmol), 1,3-bis(diphenylphosphino)propane (631 mg, 1.52 mmol), and potassium carbonate (2.55 g, 18.5 mmol) in n-propanol (45 mL) and DMF (15 mL) was stirred at 90° C. under carbon monoxide atmosphere. The mixture was allowed to stand and cool to room temperature, and then filtered through Celite. Aqueous sodium bicarbonate solution was added to the filtrate, which was extracted with ethyl acetate. The organic phase was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was evaporated off in vacuo. The residue was purified by column chromatography on silica gel (chloroform/methanol=100/1 to 50/1) to give the title compound (1.86 g, 10.3 mmol, yield 67%).
