Abstract

La presente invención se refiere a procedimiento para preparar derivados de ácidos quinilincarboxílicos de fórmula: caracterizado porque comprende reaccionar un compuesto de fórmula: en donde R es un grupo alquilo inferior de 1 a 3 átomos de carbono con formaldehido de ácido fórmico a una temperatura comprendida entre la temperatura ambiente y la temperatura de reflujo, para obtener el compuesto de fórmula: en donde R se define como anteriormente, e hidrolizar el ester al ácido carboxílico, usando u ácido tal como ácido clorhídrico, ácido acetico, o un hidróxido de metal alcalino tal como hidróxido sódico, hidróxido potásico, a temperaturas de 40 a 100 grados C.The present invention relates to a process for preparing quinyl carboxylic acid derivatives of the formula: characterized in that it comprises reacting a compound of the formula: wherein R is a lower alkyl group of 1 to 3 carbon atoms with formic acid formaldehyde at a temperature between room temperature and reflux temperature, to obtain the compound of formula: where R is defined as above, and hydrolyze the ester to carboxylic acid, using u acid such as hydrochloric acid, acetic acid, or an alkali metal hydroxide such as sodium hydroxide, potassium hydroxide, at temperatures from 40 to 100 degrees C.
