Abstract

Se proporciona un procedimiento para la preparación de 5,6,7,8-tetrahidro[1,2,4]-triazolo[4,3-a]pirazinas sustituidas que son útiles en la síntesis de inhibidores de la dipeptidil peptidasa-IV para el tratamiento de la diabetes tipo 2. También se proporcionan productos intermedios útiles obtenidos en el procedimiento. Reivindicación 1: Un procedimiento para preparar un compuesto de fórmula estructural (1) o una sal ácida del mismo, en la que R1 es fenilo opcionalmente sustituido o alquilo C1-4 insustituido o sustituido con uno a cinco átomos de F; y R2, R3, R4, y R5 son cada uno de forma independiente H, alquilo C1-4 o bencilo opcionalmente sustituido; o R2 y R3 tomados juntos con los átomos de C a los que están unidos forman un anillo alifático cíclico de 5 a 7 miembros, que comprende la etapa de ciclar un compuesto de fórmula estructural IV en un disolvente orgánico adecuado.
