Abstract

Inventia se refera la un procedeu pentru prepararea unor derivati de 6-halo--4-oxo-7--(1-piperazinil)-1,8-maftiridina reprezentati prin formula generala I: (vezi formula) în care X reprezinta un atom de halogen si R este un atom de hidrogen sau o grupa alchil inferior. Procedeul consta în aceea ca, un derivat de 6-halogen-4-oxo-1,8-naftiridina reprezentat prin formula generala II: (vezi formula) în care X are semnificatia de mai sus, R3 este un atom de hidrogen, sau o grupa protectoare si R4 este o grupa carboxil, o grupa alcoxi carbonil inferioara sau grupa R'4, în care R'4 este o grupa cian, una carbamoil, una amidina sau o grupa (vezi formula) alchil inferior reactioneaza un agent de etilare ales dintr-un grup din care fac parte halogenuri de etil, dietilsulfat, p-toluensulfat de etil si trietil fosfat, la 25...150 degree C,...
