Zusammenfassung:The present invention relates a novel process for preparing a compound of Formula I, wherein, R1, R2, R3a, R3b, R3c, R4, R5, R6, R7 and Z are as defined in the description. The process comprises a novel and inventive step of converting a dione of Formula II into an isatoic anhydride of Formula V in a single step, wherein, R2 is F, Cl, Br or I; R1, R3a, R3b, R3c, R4, R5, R6, R7 and Z are as defined in the description. La presente invención se refiere a un nuevo proceso para preparar un compuesto de fórmula I, (ver Fórmula) en donde, R1, R2, R3a, R3b, R3c, R4, R5, R6, R7 y Z son como se definen en la descripción. El proceso comprende una etapa nueva e inventiva de convertir una diona de fórmula II en un anhídrido isatoico de fórmula V en una sola etapa. (ver Fórmulas), en donde, R2 es F, Cl, Br o I; R1, R3a, R3b, R3c, R4, R5, R6, R7 y Z son como se definen en la descripción.
