Procedure

A round bottom flask was charged with 5-methoxyoxindole (100 mg, 0.61 mmol), 3-(6-Morpholinopyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole-6-carbaldehyde (266 mg, 0.61 mmol), piperidine (6 uL, 0.06 mmol) and MeOH (4 mL). The reaction was then heated to 60° C. for 4 h. An orange precipitate formed which was further precipitated by cooling to room temperature. The orange powder was then filtered and washed with MeOH to give the title compound (224 mg, 63%). 1H NMR (400 MHz, DMSO-d6) 10.46 (s, 1H), 8.79 (d, J=1.5 Hz, 1H), 8.20 (d, J=8.5, 1H), 8.17-8.13 (m, 2H), 7.77 (s, 1H), 7.57 (d, J=8.3 Hz, 1H), 7.13 (s, 1H), 7.01 (d, J=8.5 Hz, 1H), 6.85 (d, J=8.5 Hz, 1H), 6.80 (d, J=8.5 Hz, 1H), 5.82 (s, 2H), 3.73 (t, J=4.3 Hz, 4H), 3.62-3.53 (m, 9H), 0.82 (t, J=8.2 Hz, 2H), −0.12 (s, 9H); MS ESI 584.3 [M+H]+, calcd for [C32H37N5O4Si+H]+ 584.26.
