Procedure
5-Chloro-N2-(2-isopropoxy-5-methyl-4-piperidin-4-yl-phenyl)-N4-[2-(propane-2-sulfonyl)-phenyl]-pyrimidine-2,4-diamine (Example 7, 0.087 mmol) is dissolved in anhydrous DMF (1 mL). TEA (0.04 mL, 0.262 mmol, 3 equiv.) is added followed by 2-bromo-ethanol (0.019 mL, 0.262 mmol, 3 equiv.) dissolved in anhydrous DMF (0.7 mL). The reaction vessel is sealed and heated at 70° C. for 12 h. After cooling to room temperature, the reaction is diluted with ethyl acetate and washed with 1 N aqueous NaOH (5×), the organic layer is then dried over Na2SO4 and filtered. After concentration, the crude product is purified using preparative RP LC-MS to give 2-[4-(4-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-2-methyl-phenyl)-piperidin-1-yl]-ethanol (72) as a yellow powder: ESMS m/z 602.2 (M+H+).
