摘要:The present invention relates to two novel, efficient and one-pot methods for synthesizing chlorantraniliprole. In the first scheme, Chlorantraniliprole is prepared by a novel telescopic process starting from 3-Bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxylic acid a key raw material-A (Key RM-A). In the second scheme, starting from Key RM-A, the process steps use of a novel variant of anthranilic acid (Methyl 2-amino-5-chloro-3-methylbenzoate), to get Chlorantraniliprole. Furthermore, the present invention also relates to the synthesis of key starting material for the synthesizing chlorantraniliprole in-situ. All the in-situ steps of the disclosed synthesis methods obtain good yield, without using any expensive reagent or base or harsh reaction conditions, which makes the process simple, environment friendly and more cost effective. With this process the production cost of chlorantraniliprole and its intermediates is substantially reduced; fewer by-products are formed during its synthesis and since it's a one-pot reaction, isolation and purification are easy to achieve.
