Reaction Steps

To a solution of N-(2-oxoindolin-5-yl)acetamide (19 mg, 0.1 mmol) was added 1H-indazole-6-carbaldehyde (16 mg, 0.12 mmol), piperidine (2 uL, 0.011 mmol) and MeOH (2 mL). The reaction was then heated to 85° C. for 30 min. The MeOH was removed in vacuo and the solid triturated with ether to give 11 mg, 34% of the title compound as an orange solid. 1H NMR (400 MHz, CD3OD) δ 8.13 (s, 1H), 8.06 (s, 1H), 7.92-7.88 (m, 2H), 7.84 (s, 1H), 7.49 (d, J=8.6 Hz, 1H), 7.35 (d, 1H), 6.88 (d, J=8.3 Hz, 1H), 2.04 (s, 3H); MS ESI 319.1 [M+H]+, calcd for [C18H17N5O3S+H]+ 319.11.
