Reaction Steps

To a solution of 2 g (7.12 mmol) 2-chloro-5-[(4-methoxybenzyl)oxy]-3-methylpyrimidin-4(3H)-one in 20 ml TI-IF was added 521 mg (0.712 mmol) 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane adduct, 1.33 g (9.62 mmol) 3-hydroxyphenylboronic acid, and 11.4 ml (11.4 mmol) 1 M aq Cs2CO3. The reaction mixture was heated to 120° C. for 30 min in the microwave, then diluted with 10 ml water, extracted with 100 ml EtOAc, dried over Na2SO4, filtered, and concentrated in vacuo. Purification by flash chromatography (50 g silica gel, 0-100% EtOAc:hexane) gave 340 mg (14% yield) of 2-(3-hydroxyphenyl)-5-[(4-methoxybenzyl)oxy]-3-methylpyrimidin-4(3H)-one. LCMS [M+H]+=339.0.
