Procedure

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, 15 mg, 0.025 mmol) and triethylamine (37.5 uL, 0.25 mmol) in DMF (0.5 mL), is added ethyl chloroformate (5.4 mg, 0.05 mmol). The mixture is stirred at room temperature for 1 hour. The crude reaction mixture is purified by mass-trigger preparative RP LC-MS to afford the title compound 4-(6-{5-chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-1-carboxylic acid ethyl ester (175) as a white solid. 1H NMR 400 MHz (DMSO-d6 with trace D2O) δ 8.55 (d, 1H), 8.32 (s, 1H), 8.14 (s, 1H), 7.82 (dd, 1H), 7.74 (t, 1H), 7.34 (t, 1H), 7.28 (s, 1H), 4.73 (m, 2H), 4.39 (s, 2H), 4.12 (m, 2H), 4.06 (q, 2H), 3.46 (m, 1H), 2.92 (m 2H), 1.76 (m, 2H), 1.68 (m, 2H), 1.29 (d, 6H), 1.20 (t, 3H), 1.17 (d, 6H); MS m/z 671 (M+1).
