In the present work, we have studied a modified Bischler-Möhlau reaction - synthesis of indoles from benzoin and aniline. Our proposed modification of this method differs from that described earlier in that the reaction is carried out at a lower temperature, which made it possible to improve yields and reduce formation of tarry side products. In addition, unlike previous contradictory works, which described the preparation of a single 4-hydroxy or 6-hydroxy isomer in condensation of m-aminophenol and benzoin, we have obtained both 4-hydroxy and 6-hydroxy isomers.
