Procedure

{4-[(2-Methylpyridin-4-yl) oxy] phenyl} amine (47.5 g, 237 mmol) and 2-amino-4,6-dichloropyrimidine (40.8 g, 249 mmol) were suspended in water (900 mL) and 2-propanol (300 mL). 2M aqueous hydrochloric acid solution (23.7 mL) was then added and the mixture was then heated at 95° C. for 17 h. The mixture was then allowed to come to rt and solids were collected by suction filtration and washed with small amount of isopropanol. The solids were then resuspended in DMF and heated at 90° C. Triethylamine (20 mL) was then added and the mixture was stir for additional 10 min at 90° C. Water was then added in excess until cloudiness persisted at temperature. This was cooled to about 5° C. and precipitate formed were collected by suction filtration, washed with water and dried in vacuum oven at 40° C. to afford desired product (50 g, 64%) as light tan solid. 1H NMR (DMSO-d6) δ 9.40 (s, 1H), 8.27 (d, 1H), 7.76 (d, 2H), 7.06 (d, 2H), 6.75 (brs, 2H), 6.72 (d, 1H), 6.66 (s, 1H), 5.98 (s, 1H); MS ES 328 (M+H)+, calcd 328, RT=1.45 min.
