摘 要:以2-氯烟酸为原料,在强碱环境下与苯酚缩合,然后通过多聚磷酸脱水,硼氢化钾还原,再经过酸性水解,最后与氯乙酰氯进行酰化反应后,在碱性条件下发生水解反应,经磺酰氯酰化,最终通过重排得到普拉洛芬。此工艺不仅避免使用氯化锌和氰化钾,同时也减少了副反应,总收率23.7%,工艺稳定可行。 |

Abstract:Pranoprofen was synthesized from 2-chloronicotinic acid and phenol in several steps,such as condensation in alkali medium,polyphosphoric acid catalyzed dehydration,potassium borohydride reduction,followed by acidic hydrolysis,acetylation and rearrangement. The overal yield was 23.7%. The obvious advantage of this process is that it not only avoids using zinc chloride and potassium cyanide,but also decreases side reactions. |
Key words:pranoprofen;NSAIDs;synthesis |
