| 以嗎啡啉和3,4-二氟硝基苯為原料,經(jīng)取代,還原,重氮化-鹵化反應(yīng)合成中間體3-氟-4-嗎啉基溴苯(4);以(R)-環(huán)氧氯丙烷、氰酸鉀、鄰苯二甲酰亞胺鉀鹽為原料合成中間體(R)-5-鄰苯二甲酰亞胺甲基-2-噁唑烷酮(6)。然后對(duì)(4)和(6)進(jìn)行縮合、水解合成利奈唑胺?偸章视晌墨I(xiàn)報(bào)道的11%左右提高至26%。該合成工藝提高了反應(yīng)收率,降低了生產(chǎn)成本,有利于工業(yè)化生產(chǎn)。 |

| With morphine Lin and 3, 4 - two fluorine nitrobenzene as raw material via substitution, reduction, diazotization - halogenating reaction synthesis intermediates 3 - fluorine - 4 - morpholine base bromobenzene (4); To (R) - epoxy chloropropane, potassium cyanate, adjacent benzene 2 formyl imine potassium as raw materials synthesis intermediates (R) - 5 - adjacent benzene 2 formyl imine methyl - 2 - oxazole hydride ketone (6). Then (4) and (6) condensation, hydrolysis synthetic rina azole amine. The total yield is increase to 26% comparede to 11% of the reported in the literature. The synthesis process improved the yield and reduced the production cost, which be helpful for industrial production. |
