A mixture of 6-chloropyrimidin-4-amine (0.324 g, 2.5 mmol), pyridin-3-ylboronic acid (0.384 g, 3.13 mmol), Na2CO3 (0.795 g, 7.50 mmol) and bis(triphenylphosphine)palladium(II)chloride (0.035 g, 0.050 mmol) was suspended in a mixture of DME/EtOH/water. The mixture was heated in the microwave synthesizer at 125° C. for 20 min and concentrated. The residue was purified by silica gel chromatography (10-60% ethyl acetate in hexanes, then 5-25% 9:1 methanol:ammonium hydroxide-ethyl acetate) to afford 6-(pyridin-3-yl)pyrimidin-4-amine (0.17 g, 0.987 mmol, 40% yield) as an off-white solid. LCMS R.T.=0.31;
