  ChEBI: 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole is a member of beta-carbolines. |  [General Description]
 
 Ozonolysis of the enamine bond of 1,2,3,4-tetrahydro-9H-pyrido[3,4-b]indole derivatives was studied.  |  [Synthesis]
 
 1.5 g of tryptamine was dissolved in a mixed acetic acid/methanol solvent (AcOH/MeOH = 10:1, v/v) and 345 mg of paraformaldehyde was slowly added. The reaction mixture was stirred at 80 °C for 30 min. After completion of the reaction, the progress of the reaction was monitored by TLC. The reaction system was slowly poured into dilute aqueous ammonia solution (NH4OH/H2O = 1:1, v/v, 80 ml) and the pH was adjusted to 10. The organic phases were combined by extracting three times with a solvent mixture of dichloromethane/methanol (CH2Cl2/MeOH = 10:1, v/v). The organic phase was dried with anhydrous sodium sulfate, filtered and concentrated. The crude product was purified by silica gel column chromatography with dichloromethane/methanol (CH2Cl2/MeOH = 10:1, v/v) as eluent to give 1.6 g of Intermediate A in 98% yield. The product was a light yellow solid, stable at room temperature.  |  [in vivo]
