Patent ID: 7803947

Claim:
A method of producing an O-aryl N-(6-alkoxy-2-pyridyl)-N-alkylthiocarbamate represented by formula (I): (wherein R 1 and R 2 , independent of each other, denote C 1 -C 4 alkyl groups and Ar denotes an aryl group), comprising treating a phenol represented by formula (IV): Ar—OH (IV) (wherein Ar is as defined above) with a base in a solvent, adding thereto an alkali metal salt of N-(6-alkoxy-2-pyridyl)-N-alkyldithiocarbamic acid represented by formula (III): (wherein R 1 and R 2 are as defined above, and M denotes an alkali metal) and a halomethane represented by formula (V): CH 2 X m Y n (V) (wherein X and Y denote different halogen atoms, m denotes 0, 1 or 2, n denotes 0, 1 or 2, and m+n=2), and allowing to react to produce said O-aryl N-(6-alkoxy-2-pyridyl)-N-alkylthiocarbamate represented by formula (I).
