INTERMEDIATE FOR PRODUCTION OF E-OXIME ETHER OF PHENYL GLYOXYLIC ACID ESTER

摘要

PROBLEM TO BE SOLVED: To provide 2-phenoxymethylbenzoyl isocyanide and a method for production of the same which is an intermediate for production of E-oxime ether of a phenyl glyoxylic acid ester useful as a plant protective. SOLUTION: This method produces the 2-phenoxymethylbenzoyl isocyanide of formula (VI) by producing a 2-phenoxymethyl benzoic acid of formula (IV) from a phenolic compound of formula (II) and a lactone of formula (II), reacting the product with phosgene or the like to obtain corresponding benzoyl chloride and then subjecting to a cyanization. (X and Y are each a halogen atom, a 1-4C alkyl group or the like, m is an integer of 0 to 4 and n is an integer of 0 to 3).
