Reaction Steps

To a mixture of 6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-2-piperidin-4-yl-2,3-dihydro-isoindol-1-one (Example 1, 20 mg, 0.033 mmol) and triethylamine (23 uL, 0.165 mmol) in DMF (1.5 mL), is added 2-bromo-acetamide (10 mg, 0.066 mmol). The mixture is stirred at 60° C. for 4 hours. The reaction is filtered and the filtrate is purified by mass-trigger preparative RP LC-MS to afford the title compound 2-[4-(6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidin-1-yl]-acetamide (136) as a white solid: 1H NMR (400 MHz, MeOD-d4) δ 8.41 (d, 1H), 8.27 (s, 1H), 8.21 (br, 1H), 7.93 (dd, 1H), 7.73 (m, 1H), 7.40 (dd, 1H), 7.30 (s, 1H), 4.52 (s, 2H), 4.45-4.37 (m, 1H), 4.19-4.15 (br, 2H), 3.87-3.78 (br, 2H), 2.37-2.19 (m, 2H), 2.20-2.15 (m, 1H), 1.40 (d, 6H), 1.25 (d, 6H); ESMS m/z 656.2 (M+H+).
