METHOD FOR PREPARING 2,3-DIALKYLQUINOLINES Russian patent published in 2007 - IPC C07D215/04

Abstract RU 2309952 C1

FIELD: organic chemistry, organic synthesis, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of 2,3-dialkylquinolines. Invention describes a method for synthesis of 2,3-dialkylquinolines of the general formula: wherein R means C₂H₅, C₃H₇, C₄H₉ by interaction of aniline of the formula: C₆H₅NH₂ with aliphatic aldehydes of the general formula: R-CH₂CHO (wherein R has above given values) in the presence of a catalyst and wherein terbium nitrate crystal hydrate of the formula: Tb(NO₃)₃ x 6 H₂O in the mole ratio C₆H₅NH₂ : R-CH₂CHO : Tb = 45:100:1.2, and reaction is carried out in dimethylsulfoxide (DMSO) medium as a solvent under atmosphere pressure and temperature 20°C for 10 min. Invention provides simplifying technology in synthesis of the end product.

EFFECT: improved method of synthesis.
