| 摘要 |
The invention relates to a process for preparing 2-nitro-5-(phenylthio)anilines of formula (I)whereinR1 represents hydrogen, C1-C8-alkyl, C3-C8-cycloalkyl, C1-C8-alkoxy, or halogen andR2 represents hydrogen, C1-C8-alkyl, C3-C8-cycloalkyl, C1-C8-alkoxy, halogen, or C6-C10-aryl optionally substituted with C1-C8-alkyl, C1-C8-alkoxy, or halogen, by reacting, in a solvent, a 5-chloro-2-nitroaniline of the formula (II)wherein R1 is as defined for formula (I),with a thiophenol of the formula (III)wherein R2 is as defined for formula (I), andammonia. |
