Abstract
PROCEDIMIENTO DE PREPARACION DE N-METIL-3-FENIL-3-(P-TRIFLUOROMETILFENOXI)PROPILAMINA. CONSTA DE LAS SIGUIENTES ETAPAS: HACER REACCIONAR BENZALDEHIDO CON BROMURO DE ALILMAGNESIO PARA OBTENER 1-FENIL-3-BUTEN-1-OL; TRANSFORMAR ESTE EN 4-FENIL-4-(P-TRIFLUOROMETILFENOXI)BUTENO POR REACCION CON 4-TRIFLUOROMETILFENOL EN PRESENCIA DE TRIFENILFOSFINA Y AZODICARBOXILATO DE DIETILO; TRANSFORMAR EL PRODUCTO OBTENIDO EN 3-FENIL-3-(P-TRIFLUOROMETILFENOXI)PROPANAL MEDIANTE REACCION CON TETROXIDO DE OSMIO Y PERYODATO SODICO; TRANSFORMAR EL PRODUCTO OBTENIDO EN EL PRODUCTO (I) DEL TITULO POR REACCION CON METILAMINA EN CONDICIONES DE FORMACION DE LA CORRESPONDIENTE IMINA, Y POSTERIOR REDUCCION CVAIN SITU DE LA IMINA FORMADA, MEDIANTE CIANOBOROHIDRURO SODICO. FINALMENTE EL PRODUCTO (I) SE TRANSFORMA EN SU HIDROCLORURO MEDIANTE LA ADICION DE CLORURO DE HIDROGENO. LA INVENCION TIENE UTILIDAD PARA LA PREPARACION INDUSTRIALMENTE VENTAJOSA DE (I).PROCEDURE FOR THE PREPARATION OF N-METHYL-3-PHENYL-3- (P-TRIFLUOROMETHYLPHENOXY) PROPYLAMINE. CONSISTS OF THE FOLLOWING STAGES: REACTION WITH BENZALDEHYDE WITH ALYLMAGNESIUM BROMIDE TO OBTAIN 1-FENYL-3-BUTEN-1-OL; TRANSFORM THIS INTO 4-PHENYL-4- (P-TRIFLUOROMETILFENOXI) BUTENE BY REACTION WITH 4-TRIFLUOROMETILFENOL IN THE PRESENCE OF TRIPHENYLPHOSPHINE AND DIETHYL AZODICARBOXYLATE; TRANSFORM THE PRODUCT OBTAINED IN 3-PHENYL-3- (P-TRIFLUOROMETILFENOXI) PROPANAL THROUGH REACTION WITH OSMIO TETROXIDE AND SODIUM PERYODATE; TRANSFORM THE PRODUCT OBTAINED INTO PRODUCT (I) OF THE TITLE BY REACTION WITH METHYLAMINE IN CONDITIONS OF FORMATION OF THE CORRESPONDING IMINE, AND SUBSEQUENT REDUCTION OF THE FORMED IMINE, THROUGH SODIUM CYANOBOROHIDRIDE. FINALLY THE PRODUCT (I) IS TRANSFORMED INTO ITS HYDROCHLORIDE THROUGH THE ADDITION OF HYDROGEN CHLORIDE. THE INVENTION IS USEFUL FOR THE INDUSTRIAL ADVANTAGEOUS PREPARATION OF (I).
