Abstract

POBOLJŠANI POSTUPAK ZA DOBIJANJE KORISNIH DERIVATA DIAZINILPIPERIDINA, pronalazak se odnosi na poboljšani postupak, pogodan za proizvodnju u širokim razmerama, kojim se dobijaju korisni derivati diazinilpiperidina formule: gde je Z R1, R2 -disupstituisani diazin koji je vezan preko C-atoma u svom prstenu, pri čemu su R1 i R2 nezavisno H, alkil, alkoksi, alkiltio, CN, CF3, C2F5 ili halogeni, vezani za C-atome diazinskog prstena. Postupak obuhvata reakciju 2-pirolidinona i halogenometilpiridina, u prisustvu NaH, d bi se dobio intermedijer formule: koji se, u obliku vodenog rastvora svoje halogenohidratne soli, podvrgava katalitičkoj hidrogenaciji da bi se dobilo jedinjenje formule: gde je Y halogen, nakon čega se dobijeni rastvor alkalizuje i tretira sa diazinskim reagensom Z-Q, gde je Q odlazeća grupa, čime se dobija jedinjenje formule (I) kao korisno sredstvo za poboljšanje cerebralne funkcije.The invention relates to an improved process suitable for large-scale production to give useful diazinylpiperidine derivatives of the formula: wherein Z is R1, R2 is a -disubstituted diazine attached via C wherein R 1 and R 2 are independently H, alkyl, alkoxy, alkylthio, CN, CF 3, C 2 F 5 or halogen, attached to the C-atoms of the diazine ring. The process comprises reacting 2-pyrrolidinone and halogenomethylpyridine, in the presence of NaH, d to give an intermediate of formula: which, in the form of an aqueous solution of its halide salt, is subjected to catalytic hydrogenation to give a compound of formula: wherein Y is halogen, followed by the solution is alkalized and treated with the diazine reagent ZQ, wherein Q is a leaving group, to give a compound of formula (I) as a useful agent for improving cerebral function.
