| titleOfInvention | A PROCEDURE FOR PREPARING 6,7-DIALCOXY-2-METHYL-4-OXOTE-TRAHYDROQUINOLINE-1-CARBOXYLATES. |
| abstract | A process for preparing alkyl-6,7-dialkoxy-2-methyl-4-oxotetrahydroquinoline-1-carboxylates of the formula ** (See formula) ** in which R, R1 and R2 are each an alkyl having 1 to 4 carbon atoms, characterized in that a compound of formula II ** (See formula) ** wherein R2 and R1 are as defined above, is hydrogen, an alkyl having 1 to 6 carbon atoms, phenyl, phenylalkyl, substituted phenyl or substituted phenylalkyl, and R4 is hydrogen or -COOR, where R is as defined above, it is subjected to intramolecular Friedel-Crafts acylation, with subsequent isolation of the desired product, or with subsequent reaction of the resulting product with a compound of the formula X-COOR where X is bromine, chlorine, alkoxy, phenoxy, or substituted phenoxy, and R is as defined above.
