[0179] 1,9-Dimethyl-β-carboline-7-ol:
[0180] Synthesis of 1,9-Dimethyl-β-carboline-7-ol:
[0181] (a) Synthesis of 7‐methoxy‐1,9‐dimethyl‐β‐carboline:
[0182] Add dehydrohaeline (2.12g, 10mmol) and DMF (50ml) into a 100ml eggplant-shaped bottle, stir well, add NaH (0.8g, 20mmol) and stir for 10min, then add iodomethane (1.73ml, 15mmol) and stir at room temperature , TLC tracking detection. After the reaction was completed, the reaction solution was poured into 200 ml of ice water, and extracted three times with ethyl acetate. The organic phases were combined, washed with water and saturated brine. Add saturated hydrogen chloride-ethanol solution to the organic phase to pH = 2-3, distill under reduced pressure, recrystallize from acetone, and filter to obtain a yellow solid. The above solid was dissolved in 100ml of water, with NaHCO 3 Adjust pH=8‐9, extract with ethyl acetate three times, combine organic phases, wash with water and saturated brine. The org...

[0194] Synthesis of 9-n-butyl-1-methyl-β-carboline-7-ol:
[0195] (a) Synthesis of 9-n-butyl-7-methoxy-1-methyl-β-carboline:
[0196] Add dehydrobamaline (2.12g, 10mmol) and DMF (50ml) into a 100ml eggplant-shaped bottle, stir well, add NaH (0.8g, 20mmol) and stir for 10min, then add iodo-n-butane (1.38ml, 15mmol ) Stirring at room temperature, followed by TLC detection. After the reaction was completed, the reaction solution was poured into 200 ml of ice water, and extracted three times with ethyl acetate. The organic phases were combined, washed with water and saturated brine. Add saturated hydrogen chloride-ethanol solution to the organic phase to pH = 2-3, distill under reduced pressure, crystallize acetone, and filter to obtain a yellow solid. The above solid was dissolved in 100ml of water, with NaHCO 3 Adjust the pH to 8‐9, extract 3 times with ethyl acetate, combine the organic phases, wash with water, and wash with saturated brine.
