Abstract
Inventia se refera la un procedeu pentru prepararea unor 1-aril-2-aminotanoli cu formula generala I (vezi formula) în care Ar reprezinta un radical fenil, naftil, piridil, tienil, sau furil, X reprezinta unul sau mai multi substituenti alesi dintre atomi de hidrogen, fluor, clor, brom sau o grupa alchil inferior sau alcoxi inferior alcoxialchil, nitro, izonitril, dialchilamino, R1 reprezinta un atom de hidrogen, o grupa alchil inferior, cînd R2 si R3 sînt aceasi sau diferiti reprezinta un atom de hidrogen, o grupa alchil inferior, si anume sulfura de metilalchil cu formula generala II (vezi formula) în care R reprezinta un radical alchil inferior reactioneaza cu sulfat de dimetil, în mediu de solvent organic nemiscibil cu apa ales dintre clorura de metilen sau benzen, amestecul de reactie obtinut reactioneaza cu un hidroxid de metal alcalin, sau cu solutie apoasa saturata de hidroxid alcalin, în prezenta de catalizator, clorura sau bromura de tetrabutilamoniu si apoi cu un compus cu formula generala III (vezi formula) în care Ar, X si R1 au semnificatiile de mai sus, dupa care, îndepartîndu-se apa si/sau o parte din solventul organic, reziduul reactioneaza cu amoniacul sau cu o amina cu formula generala IV R2 - NH - R3 în care R2 si R3 au semnificatiile de mai sus, dupa care produsul obtinut se separa si se purifica prin metode cunoscute.
