Abstract

Un procedimiento para preparar un compuesto de la formula (5) que comprende hacer reaccionar un compuesto de la formula (4) con una base de carbonato enel seno de un disolvente a base de un alcohol. El compuesto de la formula (4) se prepara haciendoreaccionar un compuesto de la formula (3) con un reactivode metil-Grignard en el seno de un disolvente inerte. El compuesto de la formula (3) se prepara haciendo reaccionar un compuesto de formula (2) conanhídrido acético y una base amínica en el seno de un disolvente clorado. El compuesto de la formula (2) se prepara haciendo reaccionar un compuesto deformula (1) con un alcohol en un medio ácido para formar un grupo de éster. El presente incluye también nuevos compuestos de la formula (3) en laque R esalquilo C1-6 y de la formula (5).A process for preparing a compound of the formula (5) which comprises reacting a compound of the formula (4) with a carbonate base in a solvent based on an alcohol. The compound of the formula (4) is prepared by reacting a compound of the formula (3) with a methyl-Grignard reagent in an inert solvent. The compound of the formula (3) is prepared by reacting a compound of the formula (2) with acetic anhydride and an amine base within a chlorinated solvent. The compound of the formula (2) is prepared by reacting a deformula compound (1) with an alcohol in an acidic medium to form an ester group. The present also includes new compounds of the formula (3) in which R is C1-6 alkyl and of the formula (5).
