Procedure

To a solution of N4-methyl-N4-(3-methyl-1H-indazol-6-yl)-N2-{3-[(methylsulfonyl)methyl]phenyl}-2,4-pyrimidinediamine (Example 23) (389 mg, 0.92 mmol) in DMF (4 ml) was added Cs2CO3 (600 mg, 1.84 mmol) followed by iodomethane (64 ul, 1.02 mmol). The mixture was stirred at rt overnight. The mixture was diluted with water and extracted with EtOAc. The organic layer was washed with brine, dried over MgSO4, filtered and evaporated. Purification of crude product by prep TLC provided 120 mg N4-(2,3-dimethyl-2H-indazol-6-yl)-N4-methyl-N2-{3-[(methylsulfonyl)methyl]-phenyl}-2,4-pyrimidinediamine. 1H NMR (300 MHz, d6DMSO) δ 9.23 (s, 1H), 7.84-7.86 (m, 2H), 7.74 (d, J=8.8 Hz, 1H), 7.64 (d, J=7.9 Hz, 1H), 7.42 (s, 1H), 7.18 (t, J=7.8 Hz, 1H), 6.85-6.90 (m, 2H), 5.81 (d, J=5.8 Hz, 1H), 4.23 (s, 2H), 4.04 (s, 3H), 3.45 (s, 3H), 2,83 (s, 3H), 2.61 (s, 3H). MS (ES+, m/z) 437 (M+H).
