Abstract

La presente se refiere a derivados que son adecuados como precursores de compuestos útiles para obtener imágenes de depósitos amiloides en pacientes vivos, a sus composiciones, a métodos de uso y a procesos para preparar dichos compuestos. Los compuestos que derivan de estos precursores son útiles en métodos de imaginología in vivo de depósitos amiloides en el cerebro para permitir el diagnóstico ante mortem de la enfermedad de Alzheimer mediante tomografía por emisión de positrones (PET) así como la medición de la eficacia clínica de agentes terapéuticos para la enfermedad de Alzheimer. Además, la presente también divulga los compuestos precursores en forma cristalina. Reivindicación 1: Un compuesto o una de sus sales, donde el compuesto es el éster terc-butílico del ácido [6-(5-etoximetoxi-benzofuran-2-il)-2-nitro-piridin-3-il]-metil-carbámico. Reivindicación 5: El compuesto o una de sus sales de acuerdo con la reivindicación 1, en una forma cristalina que comprende los picos de difracción siguientes: 11,27; 12,00; 13,51; 15,53; 16,82; 17,91; y 23,72 º2q. Reivindicación 8: El uso de acuerdo con la reivindicación 6 ó 7, donde el compuesto marcado es 2-(6-[¹⁸F]-flúor-5-metilamino-piridin-2-il)-benzofuran-5-ol o una de sus sales.
