Reaction Steps

To a solution of 750 mg (4.30 mmol) 2-chloro-5-methoxy-3-methylpyrimidin-4(3H)-one in 20 ml THF was added 314 mg (0.430 mmol) 1,1′-bis(diphenylphosphino)ferrocene-palladium(H)dichloride dichloromethane adduct, 1.83 g (8.59 mmol) 4-phenoxyphenylboronic acid, and 4.30 ml (4.30 mmol) 1 M aq Cs2CO3. The reaction mixture was heated to 120° C. for 15 min in the microwave, then diluted with 10 ml water, extracted with 50 ml EtOAc, dried over Na2SO4, filtered, and concentrated in vacuo to give 1.33 g (100% yield) of crude 5-methoxy-3-methyl-2-(4-phenoxyphenyl)pyrimidin-4(3H)-one.
