Abstract

La invencion proporciona un proceso para preparar acilaromáticos que comprende hacer reaccionar un compuesto aromático con unácido carboxílico en lapresencia de un medio de reaccion que comprende ácido polifosforico y un ácido protico fuerte. En unaforma de realizacion, la invencion proporciona un procesopara preparar una para-acil fenoxietilamina que comprende los pasos de hacer reaccionar un compuesto 2-fenoxietilo que lleva un grupo saliente en la posicionetilo 1 con un ácido carboxílico enpresencia de un medio de reaccion que comprende ácido polifosforico y un ácido protico fuerte, para formar un intermedio depara-acil fenoxietilo que lleva el grupo saliente, y hacer reaccionar al intermedio de para-acil fenoxietilo con una amina quesustituye el grupo saliente paraformar la para-acil fenoxietilamina.
