6-Chloropyrimidin-4-amine (3.00 g, 23.14 mmol) was added to a solution of sodium (0.197 g, 8.57 mmol) in phenol (11.29 g, 120 mmol) at 55° C. The mixture was heated at 140° C. for 2 h, then held at room temperature for 20 h. The reaction mixture was poured into 32% aqueous NaOH on ice/water keeping the mixture temperature below 20° C. The mixture was extracted with chloroform and the organic extract dried over calcium chloride and concentrated. The residue was purified by silica gel chromatography (2-20% ethyl acetate in hexanes) to afford 6-phenoxypyrimidin-4-amine (0.6 g, 3.21 mmol, 75% yield) as a white solid. LCMS R.T.=1.37; [M+H]+=197.95.
