Reaction Conditions

Reaction Steps

A scintillation vial was charged with indolin-2-one (101 mg, 0.760 mmol), 1H-benzo[d][1,2,3]triazole-5-carbaldehyde (123 mg, 0.836 mmol), piperidine (7.5 uL, 0.076 mmol) and EtOH (4 mL). The reaction was then heated to 90° C. for 2 hrs. A yellow precipitate formed which was further precipitated by cooling to room temperature and adding more EtOH (5 mL). The yellow solid was then filtered and washed with EtOH (20 mL) giving 149 mg, 75% of the title compound. 1H NMR (400 MHz, d6-DMSO) δ 15.94 (s, 1H), 10.65 (s, 1H), 8.27 (bs, 1H), 8.05 (bs, 1H), 7.80 (s, 1H), 7.77 (bs, 1H), 7.51 (d, J=7.6 Hz, 1H), 7.24 (t, J=7.6 Hz, 1H), 6.88 (d, J=7.6 Hz, 1H), 6.84 (d, J=7.6 Hz, 1H); MS ESI 263.0 [M+H]+, calcd for [C15H10N4O+H]+ 263.09.
