MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202511001715 A) filed by Council Of Scientific And Industrial Research, An Indian on January 08, 2025, for Spiropidion Intermediate And A Process For The Preparation Of Spiropidion Therefrom.
Inventors include Subbarayappa Adimurthy; Sukalyan Bhadra; Subhash Chandra Ghosh; Upendra Kumar Brijmohan Patel; and Shubham.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention relates to the development of a spiropidion intermediate, specifically 2-(4-chloro-2,6-dimethylphenyl) tertiary butyl acetate (Intermediateof Formula I), along with its method of preparation. This intermediate is subsequently converted to 2-(4-chloro-2,6-dimethylphenyl)acetic acid (Intermediateof Formula II). Furthermore, the invention describes the preparation of 4-methoxy-1-(methylamino)cyclohexane-1-carbonitrile (Intermediateof Formula III), another essential spiropidion intermediate. Both intermediateof Formula II and intermediateof Formula III are crucial in the synthesis of the active agrochemical spiropidion, an effective insecticide. This invention thus provides an efficient route for the production of spiropidion using the intermediates, simplifying the manufacture of spiropidion for agricultural uses.
