Reaction Steps

(2S,4S)-4-(6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-1-oxo-1,3-dihydro-isoindol-2-yl)-pyrrolidine-2-carboxylic acid methyl ester generated in Step 1 (20 mg, 0.03 mmol) is dissolved in 7 N ammonia solution in MeOH (3 mL, 21 mmol). The resulting solution is heated using microwave irradiation to 120° C. for 1 h. After cooling to room temperature, the reaction mixture is concentrated in vacuo, neutralized to pH=8 with saturated aqueous NaHCO3, and extracted with DCM. The organic extracts are dried over Na2SO4, filtered, and concentrated in vacuo to give (2S,4S)-4-(6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-1-oxo-1,3-dihydro-isoindol-2-yl)-pyrrolidine-2-carboxylic acid amide (177) as a yellow solid. 1H NMR 400 MHz (DMSO-d6 with trace D2O) δ 8.47 (d, 1H), 8.25 (s, 1H), 8.07 (s, 1H), 7.78 (dd, 1H), 7.68 (m, 1H), 7.31 (t, 1H), 7.24 (s, 1H), 4.71 (m, 2H), 4.43 (dd, 2H), 3.60 (m, 1H), 3.44 (m, 1H), 3.35 (m, 1H), 2.63 (m, 1H), 2.28 (m, 1H), 1.22 (d, 6H), 1.10 (d, 6H); MS m/z 628 (M+1).
