Reaction Steps
To a mixture of 1H-pyrrolo[2,3-b]pyridin-2(3H)-one (26.8 mg, 0.2 mmol) and 1H-indazole-6-carbaldehyde (29.2 mg, 0.2 mmol) in MeOH (2 mL) was added 1 drop of piperidine via syringe needle. The resulting mixture was refluxed for 2 h (oil temp. 70° C.) and then cooled to rt. The resulting precipitate was collected by suction filtration to give the title compound as a yellow solid (37 mg, 71%). 1H NMR (400 MHz, DMSO-d6) δ 13.31 (s, 1H, NH), 11.25 (s, 1H, NH), 8.16 (s, 1H), 8.10 (d, J=5.2 Hz, 1H), 7.93-7.87 (m, 4H), 7.44 (d, J=8.8 Hz, 1H), 6.90 (dd, J=7.6 Hz, 5.6 Hz, 1H); MS ESI 263.0 [M+H]+, calcd for [C15H10N4O+H]+ 263.1.
