Method for preparing hexahydro-8-hydroxy-2,6-methano-2h-chinolizin-3(4h)-one esters |
| abstract |
The invention concerns a method for preparing optionally substituted 3-indolcarboxylic acid esters, with hexahydro-8-hydroxy-2,6-methano-2H-chinolizin-3(4H)-one. The invention is characterized in that the optionally substituted 3-indolcarboxylic acid is converted by means of a suitable halogenating agent, into corresponding acid halide, preferably corresponding acid chloride, and the latter is transformed with hexahydro-8-hydroxy-2,6-methano-2H-chinolizin-3(4H)-one. The invention is characterized in that the entire reaction occurs in acid medium with a maximum pH of 7. |
