Use | for intermediates in organic synthesis. |
production method | from cinnamic acid by chlorination, Acyl-amide derived. Cinnamic acid and dichlorosulfoxide were used to react at 60-70 °c for 3-4H to obtain a crude product, and the crude product was distilled under reduced pressure to obtain cinnamoyl chloride. Cinnamoyl chloride was slowly added to concentrated aqueous ammonia at 30 °c or below, and the reaction was stirred at 30 °c or below for 1H. Place 24H, poured into a large amount of distilled water, centrifugal spin drying, water washing, recrystallization with dilute ethanol to obtain the finished product. |
