실험 절차

Oxindole (665 mg, 5 mmol) and 3-iodo-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole-6-carbaldehyde (2 g, 5 mmol) were dissolved into ethanol (25 mL). Piperidine (0.1 mL) was added and the solution was heated to 70° C. for 2 h, cooled to rt and stirred overnight. The solvent was removed in vacuo to give an orange solid which was triturated with ethanol to give the title compound in quantitative yield. 1H NMR (400 MHz, CDCl3) δ 7.95 (s, 1H), 7.86 (s, 1H), 7.62-7.55 (m, 3H), 7.24 (d, 1H, J=7.8 Hz), 6.91 (d, 1H, J=7.8 Hz), 6.86 (t, 1H, J=7.6 Hz), 5.75 (s, 2H), 3.62-3.58 (m, 2H), 0.93-0.89 (m, 2H), −0.04 (s, 9H); MS ESI 518.0 [M+H]+, calcd for [C22H24IN3O2Sii+H]+ 518.4.
