Abstract

LOS ESTERES DE CADENA MAS LARGA (C SUB 6-C SUB 12) DE LOS ACIDOS DE SUSTITUCION 2-PIRIDINILOXIALCANOS, COMO EL ACETATO DE 1-METILHEPTIL (4-AMINO-3, 5-DICLORO-6-FLUOR-2-PIRIDINILOXI), SE PREPARAN CON GRAN RENDIMIENTO Y PUREZA PREPARANDO EN PRIMER LUGAR EL GRUPO METILO O ESTER METILO Y LUEGO TRANSESTERIFICANDOLOS CON UN ALCOHOL C SUB 6-C SUB 12. EL METILO O EL ESTER METILO SE PUEDE PREPARAR MEDIANTE ALKILACION DE UNA SAL METALICA ALCALINA DE 4-AMINO-3,5-DICLORO-6-FLUORO-2-PIRIDINOL CON CLOROACETATO DE METILO O ETILO Y ENTONCES SE PUEDE LLEVAR A CABO LA TRANSESTERIFICACION EN PRESENCIA DE UN CATALIZADOR DE TITANATO DE TETRAALKILO.
