Reaction Steps

A mixture of 6-chloropyrimidin-4-amine (0.32 g, 2.5 mmol), phenylboronic acid (0.38 g, 3.13 mmol), saturated aqueous sodium carbonate (0.80 g, 7.50 mmol) and bis(triphenylphosphine)palladium(II) chloride (0.035 g, 0.05 mmol) were suspended in a mixture of dimethoxyethane (15 mL)/ethanol (2 mL)/water (2 mL). The mixture was heated in the microwave at 125° C. for 20 min then concentrated in vacuo. The residue was purified by column chromatography (10-60% ethyl acetate/hexanes) to afford 6-phenylpyrimidin-4-amine (167 mg, 0.98 mmol, 39% yield) as an off-white solid. MS (LC/MS) R.T.=0.99; [M+H]+=172.23.
