| titleOfInvention | A method of producing new acridine derivatives |
| abstract | 1 The method of producing new acry derivatives S.ndyes of the formula I in which R o is hydrogen ornhhlooen, luu gmu? Ci-ialkyl, CC- " alkyxyl,nCi-ealkylthio, amino / fluoro; conclude the number 1,nor if R ° is C 1-4 alkyxyl it may alsonstand for 2 or 3; Ri is hydrogen or halogen,nor C1-4alkylqlo, C1-4alkoxy or C1-4alkylthio;nR2 is hydrogen or C1-4alkyl, Anis an oxygen or sulfur atom, a chemical bond orna group (CH2I1NR9 (where 1 is zero or 1 and R9nrepresents a hydrogen atom or a methyl group), B isna C 1-4 alkyl chain optionally substituted with a groupnhydroxyl, with reservation, ..............................nR represents a hydrogen atom or a C 1-4 alkyl group ornCi_4alkoxy, R7 is hydrogen or R3 and R7ntogether are the group - (CH21n-, where n is 1 orn2; R8 represents a hydrogen atom or a C1-4alkoxy group;nthe group of formula 1 'is attached to the benzene ringnat the 3 or 4 position relative to the carboxyramidkwegk substituent,nexcept that if this group is innposition 3 of the benzene ring, then R ^ must be foundnis at the 6-position of the benzene ring; and theirna salt of solvate 1, characterized in that the compound of formula 2, wnwherein Q is halogen is reacted with the compoundnof formula III or a salt thereof in the presence of an acid acceptor, wnwith formulas 2 and 3 all symbols have higherngiven meaning 1 optionally produces a salt or a solvatencompound of formula 1 |
