Procedure

A mixture of 5-chloro-N2-(2-fluoro-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine (400 mg, 0.96 mmol), iodoethane (92.5 μL, 1.2 mmol) and triethylamine (201.5 μL, 1.4 mmol) in 4 mL of DMF was heated at 60° C. for 2 h. The reaction mixture was partitioned between EtOAc and water. The combined organic extracts were dried (Na2 SO4) and concentrated in vacuo. The crude product was purified by silica gel chromatography (MeOH/DCM: 1/9) to afford 5-chloro-N2-(4-(1-ethylpiperidin-4-yl)-2-fluoro-5-methylphenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine; 1HNMR (DMSO-d6) δ 8.01 (s, 1H), 7.35 (m, 1H), 7.02 (d, 1H), 6.22 (s, 1H), 2.97 (d, 2H), 2.62 (m, 1H), 2.34 (q, 2H), 2.21 (s, 3H), 2.13 (s, 3H), 1.98 (t, 2H), 1.64 (m, 4H), 1.01 (t, 3H); ESMS m/z 444.2 (M+H+).
