Reaction Steps

To 4-amino-2-methyl-phenol (193 mg, 1.57 mmol) was added Cs2CO3 (1.02 g, 3.14 mmol) and NMP (2.0 mL). The mixture was heated for 5 minutes at 100° C., cooled to RT and 4-(2-chloro-pyridin-3-yl)-pyrimidine (300 mg, 1.57 mmol) was added. The mixture was heated in the microwave to 210° C. for 20 minutes, cooled, filtered through a plug of cotton and purified by reverse-phase HPLC (Gilson, acidic mobile phase) to yield 3-methyl-4-(3-pyrimidin-4-yl-pyridin-2-yloxy)-phenylamine. MS m/z=279 [M+1]+. Calc'd for C16H14N4O: 278.32.
