Methyl iodide → HCID 59455241, compound

Participants

Reaction Steps

2-(2,8-Dimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-1-pyridin-4-yl-ethanone (100 mg) was dissolved in DMF (5 mL). Sodium hydride was added at once under nitrogen atmosphere followed by addition of methyl iodide. The contents were stirred at RT overnight. The reaction was monitored by LCMS. The reaction mixture was poured into 25 mL ice cold water and extracted with EtOAc (20 mL×3). The combined organic layers were given water washing (30 mL×2), dried over sodium sulfate and concentrated under vacuum to obtain the crude product, which was purified by reverse phase column chromatography to get 2 mg product as the TFA salt. 1H NMR (CD3OD, TFA salt) δ (ppm): 8.78 (d, 2H), 8.22 (d, 2H), 7.70 (s, 1H), 7.34 (m, 2H), 7.18 (d, 1H), 4.80 (m, 1H), 4.40 (m, 2H), 3.80 (m, 1H), 3.60 (m, 1H), 3.40 (s, 3H), 3.26 (m, 2H), 3.16 (s, 3H), 2.44 (s, 3H).
