Abstract
PURPOSE: Pyrido [1, 2-a] phrimidinone derivatives of formula I [where R1 and R2 are H, lower alkyl or halogen; R3 is lower alkyl or phenyl when n is 0 and R3 is hydroxy when n is l; R4 is H or lower alkyl and R5 is lower alkyl and they may be linked together with the neighbouring N-atom to form a (substituted)cyclic amino group] and their acid adducts are new.
