85% | General procedure: Take <strong>[56293-29-9]aloperine</strong> (1) 0.5 g (0,002 mol),Was added to 20 ml of acetonitrile, and 1.8 g (0.006 mol) of anhydrous potassium carbonate and substituted bromobenzyl or benzyl chloride (0.003 mol) were successively added to the reaction solution, followed by stirring at room temperature.TLC was detected until the reaction was complete. The organic phase was concentrated and evaporated to dryness. The solvent was dissolved in dichloromethane and washed successively with water and saturated brine. The methylene chloride layer was dried and the solvent was evaporated to dryness with a rotary evaporator to give the crude 12-N-benzyl <strong>[56293-29-9]aloperine</strong> derivative. The solution was dissolved in 20 ml of methylene chloride solventAnd then separated by column chromatography to give pure product of 12-N-benzyl-<strong>[56293-29-9]aloperine</strong> derivative (2). The resulting compound was dissolved in 5 ml of ether,And then with 1N HCl / Et2O adjusted PH = 6-7, filtered, 12-N-benzyl ether alkalis derivatives pure hydrochloric acid. |
