Abstract
Un proceso para la preparacion de pirazoles sustituidos en N, de la formula general I, en donde R1 es alquilo de C1-C12 o fenilalquilo de C7-C20 y R2 y R4 son, independientemente entre sí, hidrogeno, alquilo de C1-C12-, fenilalquilo de C7-C20 o radicales arilo no sustituidos o sustituidos, mediante la reaccion de los pirazoles de la formula general II; en donde R2, R3 y R4 tienen los significados antes mencionados, con un alcohol de la formula general III, en donde R1 tiene el significado antes mencionado, a 50 - 400 degree C en presencia de un catalizador, en donde la reaccion del pirazol II con el compuesto III en la proporcion molar desde 0.001:1 a 1:1 se lleva a cabo en fase líquida bajo una presion que es ligeramente abajo de la atmosférica o hasta una presion de 250 bar y se utilizan ácidos y/o sus ésteres de alquilo o sus anhídridos, en una relacion molar desde 0.0001:1 hasta 0.5:1 con respecto al pirazol II, como catalizador.
