온도110 °C

반응 단계

1-Methyl-1H-indazol-5-ol (in) (synthesized as described in Example 94) (0.10 g, 0.68 mmol) and 2-chloro-nicotinonitrile (2n) (0.11 g, 0.81 mmol) were suspended in DMSO (2 mL). The reaction mixture was heated to 110° C. for 18 hours. The reaction mixture was diluted with water and extracted into EtOAc. The combined organics were dried, Na2SO4 and concentrated under reduced pressure to afford the crude product. Purification by flash column chromatography (20-100% EtOAc/Hexanes) furnished the desired product (3n), (0.152 g, 90% yield). 1H NMR (400 mHz, CD3OD) δ 8.27-8.25 (m, 1H), 8.23-8.20 (m, 1H), 8.01 (s, 1H), 7.62 (d, J=8.6 Hz, 1H), 7.57 (d, J=2.3 Hz, 1H), 7.28-7.26 (m, 1H), 7.23-7.20 (m, 1H), 4.10 (s, 3H); MS (ESI+) m/z 251 (M+H) detected.
