Abstract
It is an object of the present invention to provide a novel and advantageous process for commercially preparing of indoxacarb which is racemic or enantiomerically enriched at chiral center from its amide precursor using a new catalytic system. More particularly, it relates to an efficient method of preparation of indoxacarb which is racemic or enantiomerically enriched at chiral center from methyl-7-chloro-2,5-dihydro-2-[[[(4-tritluoromethoxy)phenyl]amino]carbonyl]-indeno[1,2-e][1,3,4]oxadiazine-4a(3H) carboxylate represented as formula (I) using methoxycarbonylation agent and metal salt of methylsulfinylmethylide in hydrocarbon solvent in the presence of organic base and phase transfer catalyst.
