Abstract

La invención proporciona un proceso para elaborar una anilina (2), en donde PG indica hidrógeno o un grupo protector amino, que es adecuado para la elaboración a gran escala de dicha anilina (2). Reivindicación 1: Un proceso para elaborar una anilina (2), en donde PG indica hidrógeno o un grupo protector amino seleccionado de Boc (t-butoxicarbonilo), bencilo, 4-metoxibencilo, benzhidrilo, Fmoc (fluorenilmetoxicarbonilo), Cbz (benciloxicarbonilo), Moz (p-metoxibencil carbonilo), Troc (2,2,2-tricloroetoxicarbonilo), Teoc (2-(trimetilsilil)etoxicarbonilo), Adoc (adamantoxicarbonilo), formilo, acetilo y ciclobutoxicarbonilo, que comprende: hacer reaccionar un nitroareno (1), en donde PG indica un grupo protector amino seleccionado de Boc (t-butoxicarbonilo), bencilo, 4-metoxibencilo, benzhidrilo, Fmoc (fluorenilmetoxicarbonilo), Cbz (benciloxicarbonilo), Moz (p-metoxibencil carbonilo), Troc (2,2,2-tricloroetoxicarbonilo), Teoc (2-(trimetilsilil)etoxicarbonilo), Adoc (adamantoxicarbonilo), formilo, acetilo y ciclobutoxicarbonilo, con hidrógeno (i) en presencia de un catalizador de metal de transición; (ii) en un solvente aprótico; para formar dicha anilina (2), en donde dicho solvente aprótico contiene 0,01% p/p a 0,1% p/p de agua con respecto al solvente aprótico. Reivindicación 5: El proceso de acuerdo con cualquiera de las reivindicaciones 1 a 4, en donde dicho catalizador de metal de transición se selecciona de Pt, Pd, Pt-V y Ni, en donde cada uno de dichos Pt, Pd, Pt-V y Ni está en un soporte sólido, preferentemente en donde dicho catalizador de metal de transición se selecciona de PtO₂, Pd/C, Pt-V/C, Pt/C y Raney Ni. Reivindicación 10: El proceso de acuerdo con cualquiera de las reivindicaciones 1 a 9, en donde dicho solvente aprótico es un éter. Reivindicación 11: El proceso de acuerdo con la reivindicación 10, en donde dicho éter es ter-butil metil éter (TBME). Reivindicación 21: Un proceso para elaborar 5-etil-4-metil-N-[4-[(2S) morfolin-2-il]fenil]-1H-pirazol-3-carboxamida (fórmula IV), o una sal farmacéuticamente aceptable de esta, que comprende un proceso de acuerdo con cualquiera de las reivindicaciones 1 a 19.
