Versuchsvorschrift

To a solution of NaH (84 mg, 2.1 mmol) in DMF (5 mL) at 0° C. was added trimethylsulfoxonium iodide (154 mg, 0.70 mmol). The resulting mixture was stirred at rt for 30 min followed by the addition of (E)-5-Methoxy-3-((3-(6-morpholinopyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazol-6-yl)methylene)indolin-2-one in DMF (2 mL). The reaction mixture was then heated to 55° C. for 3 h. The reaction was cooled to 0° C. and quenched with saturated NH4Cl. The mixture was extracted with EtOAc and the combined organic extracts were washed with brine, dried over MgSO4 and concentrated to give yellow viscous oil. The crude product was purified by silica gel chromatography (95:5 CH2Cl2/MeOH) to yield a bright yellow powder, which was triturated with EtOAc to give the title compound as a pale yellow powder (93 mg, 44%). 1H NMR (400 MHz, CD3OD) δ 10.45 (br. s, 1H), 8.71 (s, 1H), 8.10 (d, J=8.5 Hz, 1H), 7.93 (d, J=7.2 Hz, 1H), 7.84 (s, 1H), 7.08 (d, J=7.2 Hz, 1H), 6.98 (d, J=7.2 Hz, 1H), 6.73 (d, J=5.4 Hz, 1H), 6.56 (d, J=6.0 Hz, 1H), 5.86-5.75 (m, 3H), 3.71 (br s, 4H), 3.52 (br s, 4H), 3.40-3.16 (m, 6H), 2.42 (br. s, 1H), 2.00 (br. s, 1H), 0.79 (br s, 2H), −0.13 (s, 9H); MS ESI 598.4 [M+H]+, calcd for [C33H39N5O4Si+H]+ 598.28.
