To a solution of 4-(2-methanesulfonyl-pyrimidin-4-yloxy)-benzene-1,2-diamine (Step B, 400 mg, 1.4 mmol, 1.0 eq) in anhydrous THF (4 mL) was added 1 mL of 2 M CH3NH2 in THF (2 mmol, 1.4 eq). The solution was heated to 80° C. for 1 h. The THF was removed under reduced pressure. The crude was purified by column chromatography (0-10% MeOH/CH2Cl2 with 1% NH4OH) to yield 4-(2-methylamino-pyrimidin-4-yloxy)-benzene-1,2-diamine.
