Abstract
Compuesto que tiene la fórmula:**Fórmula** en donde R5 es -CH2CH3, o una sal farmacéuticamente aceptable del mismo.
Description
En realizaciones adicionales, la invención comprende compuestos útiles como intermediarios en la síntesis del Compuesto 15, además de en procesos para la preparación de tales intermediarios y del Compuesto 15. Por ejemplo, en tales realizaciones, la invención comprende compuestos que se muestran en los Ejemplos a continuación, tales como los Compuestos 11, 12, 13, 14, y los compuestos enriquecidos isotópicamente tales como5 los Compuestos 19,20,28,29,31,32. Una realización de este tipo es el Compuesto 15 en el que el sustituyente 4-OH en la fracción de pirrolidina está protegida con un grupo protector. Un grupo protector ilustrativo es un grupo acetilo, que se ilustra en los Compuestos 11-14, a continuación. Otros grupos protectores de utilidad resultarán evidentes para las personas expertas en el arte e incluyen, por ejemplo, grupos benzoilo, bencilo, trimetilsililo, y trifenilmetilo. El grupo protector se elimina, por ejemplo, poniendo en contacto el intermedio protegido con un ácido o una base, 10 según se muestra en los Esquemas XIII y XIV, a continuación. De ese modo, la invención comprende el compuesto que tiene la estructura del Compuesto 15 además de versiones protegidas del Compuesto 15 tales como los Compuestos 13 y 14 en los que los extremos N-terminal están protegidos con fracciones de carbamato y/o los grupos hidroxilo libres están protegidos como ésteres, donde tales compuestos se denominan Compuesto 15 protegido. La invención además comprende el paso de desproteger un Compuesto protegido 15, poniendo en
15 contacto el Compuesto protegido 15 con un ácido o base por el que el Grupo Protector se elimina para proporcionar el Compuesto 15. Los compuestos de la invención enriquecidos isotópicamente incluyen formas deuteradas del Compuesto 15 tales como los Compuestos 20, 29, y 32. Las formas protegidas de tales compuestos, por ejemplo, los Compuestos 19, 28, y 31, están también comprendidos en la invención.

Éster bencílico del ácido 2-(6-Fluoro-1H-indol-3-carbonil)-4-hidroxi-pirrolidina-1-carboxílico (4): A una solución que contiene 3 (227 g) en THF (600 mL) se añadió 1 M de TBAF en THF (160 mL) a temperatura ambiente. Después de 9 h, se añadió otros 20 mL de la solución de 1 M de TBAF/THF. Después de aproximadamente 48 h, la mezcla de reacción se concentró en vacío y a continuación se redisolvió en EtOAc (600 mL). La solución orgánica se lavó con agua (310 mL) y el producto se precipitó para formar una suspensión espesa que se filtró (lentamente). Los sólidos se lavaron con EtOAc (165 mL en porciones) y se secaron para proporcionar 43 g de 4. El filtrado combinado se concentró en vacío para precipitar 4,8 g adicionales de 4 después de secarlo. 1H RMN (300 MHz, d6-DMSO), mezcla de rotómeros: δ612.08 (br s, 1H), 8.43 (d, J = 10.5 Hz, 1H), 8.16 (ddd, J = 5.4, 8.7, 14.1 Hz, 1H), 7.36-7.31 (m, 2H),

5-(3’-{4-acetoxi-1-[2-(2-metilamino-propionilamino)-butiril]-pirrolidin-2-il-d2-metil}-6,6’-difluoro-1H,1’H-[2,2’]biindolil-3-ild2-metil)-1-[2-(2-metilamino-propionilamino)-butiril]-pirrolidin-3-il éster del ácido acético (28): Una solución que contenía 27 (170 mg, 0,15 mmol) en DCM (15 mL) se enfrió a 0 °C. Se añadió TFA (5 mL). Después de 30 min, la mezcla de reacción se dejó calentar a temperatura ambiente y se monitorizó hasta que el análisis de LC/MS reveló la conversión completa de 27 a 28 (aproximadamente 4 h). El disolvente se eliminó en vacío y el residuo de color verde, oscuro en se disolvió en EtOAc (100 mL) y se vertió cuidadosamente en una mezcla de NaHCO3/hielo acuosa. La fase acuosa se separó y se volvió a extraer con EtOAc (2 X 20 mL). Los extractos orgánicos combinados se lavaron varias veces con NaHCO3 acuoso saturado, a continuación con salmuera, se secaron sobre Na2SO4 anhidro, se filtraron, y se concentraron para proporcionar 28 crudo en forma de un sólido de color amarillo claro. Espectro de masa (ESI), m/z 895.3 [(M)+; calculado para C46H56D4F2N8O8: 895.0].
