Abstract
Procedure for obtaining derivatives of 2H-indene [1,2-c] pyridine of formula Ia, wherein RI1 is selected from the group consisting of alkyl, alkenyl, alkynyl and benzyl, R2 is selected from the group consisting of a primary lower alkyl and a secondary alkyl, and R3 is selected from the group consisting of hydrogen, halogen, and lower alkyl, with the proviso that RI1 cannot signify methyl when R2 signifies methyl and R3 signifies hydrogen, characterized in that a compound, which is selected from the group of compounds, of formula II, is cyclized, **(See formula)** where RI1, R2 and R3 have the meanings indicated above, with the proviso that RI1 does not mean methyl when R2 means methyl and R3 means hydrogen, **(See formula)** wherein RI1 and R3 have the meanings indicated above, and each of R5 and R6 is selected from the group consisting of hydrogen and a lower alkyl, with the proviso that RI1 cannot signify methyl when all symbols and R6 signify hydrogen.
