摘 要:以2-氯煙酸為原料,在強堿環(huán)境下與苯酚縮合,然后通過(guò)多聚磷酸脫水,硼氫化鉀還原,再經(jīng)過(guò)酸性水解,最后與氯乙酰氯進(jìn)行;磻,在堿性條件下發(fā)生水解反應,經(jīng)磺酰氯;,最終通過(guò)重排得到普拉洛芬。此工藝不僅避免使用氯化鋅和氰化鉀,同時(shí)也減少了副反應,總收率23.7%,工藝穩定可行。 |

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 |
