Abstract
Un proceso para la preparacion de derivados de pirazol adaptado para una reaccion "one pot" que involucra la utilizacion de un agente de ciclacion y comprende el paso de amidacion en presencia de un catalizador. También se describen los pasos para aislacion y purificacion de derivados de pirazol encontrados. Reivindicacion 1: Un proceso para la preparacion de compuestos derivados de pirazol de la Formula (2). en donde a, b, c, d, e y a' b' c' d' e' son idénticos o diferentes y son independientemente hidrogeno, un halogeno, un alquilo (C1-12), un alcoxi (C1-12), un trifluorometilo, un grupo nitro, nitroarilo, nitroalquilo y alquiltio (C1-12). R1 es hidrogeno o un alquilo (C1-12); R2 es un alquilo (C1-12); d es hidrogeno, un halogeno, un alquilo (C1-12), un alcoxi (C1-12), un trifluorometilo, un grupo nitro, nitroarilo, nitroalquilo y alquiltio (C1-12), un fenilo o alcoxifenilo o ariloxifenilo y halofenilo, X es independientemente una amina alifática, hetrocíclica y heterocíclica, caracterizado por comprende los siguientes pasos de método: a. ciclar en un recipiente de reaccion, y en atmosfera inerte un compuesto de la formula 1 mediante tratamiento con un agente de cialacion, para producir una primera masa; (1) en donde: R1 es hidrogeno o un alquilo (C1-12); R2 es un (C1-12) alquilo; a, b, c, e, y a' b' c' d' e' son idénticos o diferentes y son independientemente hidrogeno, un halogeno, un alquilo (C1-12), un alcoxi (C1-12), un trifluorometilo, un grupo nitro, nitroarilo, nitroalquilo y alquiltio (C1-12). d es hidrogeno, un halogeno, un alquilo (C1-12), un alcoxi (C1-12), un trifluorometilo, un grupo nitro, nitroarilo, nitroalquilo, alquiltio (C1-12), un fenilo o alcoxifenilo o ariloxifenilo y halofenilo. b. separar el exceso de agente de ciclacion; c. amidar la primera masa con una amina en atmosfera inerte, y en presencia de un catalizador y opcionalmente con la ayuda de un agente nucleante para producir una masa amidada; d. separar el exceso de amina de la masa amidada para producir una segunda masa; e aislar el compuesto de la Formula 2 de la segunda masa.
