Abstract

PROCEDIMIENTO PARA PREPARAR 1-[2-[(5-DIMETILAMINOMETIL-2-FURIL)-METILTIO]-ETIL]-AMINO-1-METILAMINO-2-NITROTILENO FORMULA (NOMBRTE GENERICO: RANITIDINA), QUE COMPRENDE HACER REACCIONAR EL DERIVADO DE DICETENIMINA DE LA FORMULA (II) FORMULA CON METILAMINA. LA VENTAJA MAS IMPORTANTE DE LA INVENCION CONSISTE EN QUE SE PUEDE PREPARAR RANITIDINA CON UN RENDIMIENTO DE MAS DEL 90% MEDIANTE UN PROCEDIMIENTO SENCILLO.PROCEDURE FOR PREPARING 1- [2 - [(5-DIMETILAMINOMETIL-2-FURIL) -METILTIO] -ETIL] -AMINO-1-METHYLAMINE-2-NITROTILENO FORMULA (GENERIC NAME: RANITIDINA), WHICH INCLUDES TO REACT THE DERIVATIVES OF THE FORMULA (II) FORMULA WITH METHYLAMINE. THE MOST IMPORTANT ADVANTAGE OF THE INVENTION IS THAT RANITIDINE CAN BE PREPARED WITH A YIELD OF MORE THAN 90% THROUGH A SIMPLE PROCEDURE.
