Procedure

To a solution of 4-[4-(2-amino-6-phenyl-pyrimidin-4-ylamino)-phenoxy]-pyridine-2-carbonitrile (Example 8, 200 mg, 0.53 mmol) and sodium acetate (146.6 mg, 459.8 mmol) in acetic acid (4 mL) at rt was added bromine (84 mg, 0.53 mmol). The reaction was allowed to stand for 2 h after which time dichloromethane (20 mL) was added followed by water (20 mL). The phases were separated and the organic layer was washed with a saturated aqueous bicarbonate solution. The combined organic extracts were dried over MgSO4 and then evaporated under vacuum. The crude material was purified by column chromatography eluting with a gradient of 0 to 60% AcOEt/Hexanes to give 4-[4-(2-Amino-5-bromo-6-phenyl-pyrimidin-4-ylamino)-phenoxy]-pyridine-2-carbonitrile as an orange solid (200 mg, 83%). 1H NMR (DMSO d6) δ 8.58 (d, J=5 Hz, 1H, 8.50 (Br, 1H), 7.90-7.86 (m, 2H), 7.67 (d, J=2 Hz, 1H), 7.54-7.51 (m, 2H), 7.47-7.41 (m, 3H), 7.20-7.16 (m, 3H), 6.57 (Br, 2H).
