Abstract
6. UN PROCEDIMIENTO PARA LA PREPARACION DE UN COMPUESTO DE FORMULA I QUE SE SELECCIONA DE ENTRE EL GRUPO FORMADO POR UN POLIMORFO PI NO HIGROSCO- PICO, UN POLIMORFO PII HIGROSCOPICO Y UN PENTAHI- DRATO DEL MISMO, QUE COMPRENDE: A. LAS ETAPAS DE TRATAR UNA SUSPENSION ACUOSA DE UNA FORMA METAESTABLE DEL COMPUESTO DE FORMULA I FIGURA 1 (1) CON UN DISOLVENTE NO POLAR SEGUIDA DE LA ELI- MINACION AZEOTROPICA DEL AGUA RESIDUAL Y SECADO AL VACIO PARA FORMAR DICHO POLIMORFO PII HIGROSCOPICO QUE MUESTRA EL PATRON DE DIFRACCION DE RAYOS X DE POLVO CARACTERISTICO QUE SE DESCRIBE EN LA REIVIN- DICACION 1; (2) CON UN DISOLVENTE POLAR SEGUIDA DE LA ELIMINA- CION AZEOTROPICA DEL AGUA RESIDUAL Y SECADO AL VA- CIO; (3) CON AGUA Y SECANDO EL RESIDUO CON AIRE A UNA TEMPERATURA ELEVADA, ELIMINANDO LAS AGUAS MADRES Y SECANDO EL RESIDUO CON AIRE A TEMPERATURA AMBIENTE HASTA PESO CONSTANTE PARA FORMAR EL PENTAHIDRATO; O B. TRATAR EL SEGUNDO POLIMORFO PII HIGROSCOPICO CON UN DISOLVENTE POLAR A REFLUJO PARA FORMAR EL PRIMER POLIMORFO PI NO HIGROSCOPICO.6. A PROCEDURE FOR THE PREPARATION OF A COMPOUND OF FORMULA I THAT IS SELECTED FROM THE GROUP FORMED BY A NON-HYGROSCOPIC POLYMORPH PI, A HYGROSCOPIC POLYMORPH PII AND A PENTAHYDRATE OF THE SAME, INCLUDING: A. THE STAGES OF TREAT AN AQUEOUS SUSPENSION OF A METASTABLE FORM OF THE FORMULA I COMPOUND X-RAYS OF CHARACTERISTIC POWDER DESCRIBED IN CLAIM 1; (2) WITH A POLAR SOLVENT FOLLOWED BY THE AZEOTROPIC DISPOSAL OF RESIDUAL WATER AND VACUUM DRYING; (3) WITH WATER AND DRYING THE WASTE WITH AIR AT A HIGH TEMPERATURE, ELIMINATING THE MOTHER WATERS AND DRYING THE WASTE WITH AIR AT ROOM TEMPERATURE UNTIL CONSTANT WEIGHT TO FORM THE PENTAHYDRATE; OR B. TREAT THE SECOND HYGROSCOPIC POLYMORPH PII WITH A REFLUX POLAR SOLVENT TO FORM THE FIRST NON-HYGROSCOPIC POLYMORPH PI.
