Reaction Steps

To a solution of 3-chloro-propane-1-sulfonic acid [2-(1H-indazol-4-yl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl]-methylamide (45 mg) in acetonitrile (2 mL) was added morpholine (38 μL), potassium carbonate (18 mg) and potassium iodide (2 mg). the reaction mixture was heated at 80° C. for 72 h and allowed to cool to room temperature before quenching with water (30 mL) and extracting into dichloromethane (2×30 mL). The combined organics were washed with brine (30 mL), dried (MgSO4), reduced in vacuo and purified by column chromatography to give 186 as an off-white solid (27 mg). NMR: CDCl3: 1.97 (m, 2H), 2.36-2.43 (m, 6H), 2.87 (s, 3H), 3.07 (m, 2H), 3.63 (t, J=4.6, 4H), 3.84 (t, J=4.8, 4H), 4.01 (t, J=4.8, 4H), 4.61 (s, 2H), 7.39 (s, 1H), 7.43 (t, J=8.2, 1H), 7.51 (d, J=8.3, 1H), 8.20 (d, J=6.8, 1H), 8.94 (s, 1H), 10.30 (brs, 1H).
