Abstract
Process for obtaining derivatives of 2H-indeno [1; 2-c] pyridine, of formula ia, ** (see formula) ** Wherein ri1 is selected from the group consisting of alkyl, alkenyl, alkynyl and benzyl, R2 is selected from the group consisting of primary and secondary lower alkyl, and R3 is selected from the group consisting of hydrogen, halogen and lower alkyl, with the proviso that Ri1 does not mean methyl when r2 means methyl and r3 is hydrogen, characterized in that a compound of formula ic is condensed, ** (see formula) ** Wherein r2 and r3 have the meanings indicated above, with a compound of formula iii, Ri1-y iii Where ri1 has the meaning indicated above, and And it means the acid radical of a reactive ester, with the proviso that Ri1 in the compounds of formula iii can not mean methyl when in the compounds of formula ic r2 means methyl and r3 signifies hydrogen.
