Abstract
PROCEDIMIENTO PARA PREPARAR UN MATERIAL CROMOGENO DE FORMULA (I) O DE SU ISOMERO 7-(1-ETIL-2-METILINDOL-3- IL)-7-(4-DIETILAMINO-2-ETOXIFENIL)-5,7-DIHIDROFURO (3,4-B)-PIRIDIN-5-ONA O DE UNA MEZCLA DE AMBOS. CONSISTE EN HACER REACCIONAR UN CETOACIDO DE FORMULA (II) O SU ISOMERO 2-CARBOXIPIRID-3-ILO O UNA MEZCLA DE AMBOS, CON UN COMPUESTO: B-H, DONDE UNO DE LOS RADIALES A O B ES 4-DIETILAMINO-2-ETOXIFENILO Y EL OTRO ES 1-ETIL-2-METILINDOL-3-ILO, EN PRESENCIA DE UN AGENTE DESHIDRATANTE TAL COMO ANHIDRIDO ACETICO, EFECTUANDOSE LA REACCION A UNA TEMPERATURA ELEVADA DEL ORDEN DE LOS 65 A LOS 75G. GENERALMENTE, EN EL PROCEDIMIENTO DE PREPARACION MAS FRECUENTEMENTE USADO SE OBTIENE UNA MEZCLA FORMADA POR MATERIAL CROMOGENO DE FORMULA (I) Y SU ISOMERO, SIENDO LA MEZCLA MAS USADA AQUELLA QUE CONTIENE DE UN 90 A UN 95 POR 100 DEL ISOMERO DE PIRIDIN-5-ONA. LOS ISOMEROS DE MATERIAL CROMOGENO, OBTENIDOS EN FORMA DE MEZCLA, SE PUEDEN SEPARAR UTILIZANDO TECNICAS CONVENCIONALES, QUE EL PROCESO ES COSTOSO A ESCALA COMERCIAL. *FORMULA*
