Abstract

Inventia se refera la un procedeu de preparare a unor 2-amino-benzofenone substituite, având formula generala I:(vezi formula) în care X este hidrogen sau halogen, Y este hidrogen, o la -, sau p-halogen, prin reducerea 3-fenil-antraniului, corespunzator cu formula generala II: (vezi formula) în care X si Y au semnificatiile de mai sus, în care reducerea se efectueaza cu fier si acid clorhidric, în mediu de metanol apos 95% cu un raport molar 3-fenil-antanil : acid clorhidric: fier de 1:3:1, la reflux, folosindu-se o dilutie de 5:1 în greutate metanol 3-fenil-antranil.The invention relates to a process for the preparation of substituted 2-aminobenzophenones having the general formula I wherein X is hydrogen or halogen, Y is hydrogen, o-, or p-halogen by reducing 3 -phenyl-antran, corresponding to the general formula II: wherein X and Y are as defined above, wherein the reduction is carried out with iron and hydrochloric acid in 95% aqueous methanol medium with a 3- phenyl-anthanil: hydrochloric acid: iron 1: 3: 1, at reflux, using a 5: 1 w / w solution of 3-phenyl-anthranil methanol.
