Method for producing thiocarbamate derivative

A method of producing an O-aryl N-(6-alkoxy-2-pyridyl)-N-alkylthiocarbamate represented by formula (I):

• (wherein R1 and R2, independent of each other, denote C1-C4 alkyl groups and Ar denotes an aryl group), comprising:
• causing a 6-alkoxy-2-alkylaminopyridine represented by formula (II):
• (wherein R1 and R2 are as defined above) to react with carbon disulfide in the presence of a base, to produce an alkali metal salt of N-(6-alkoxy-2-pyridyl)-N-alkyldithiocarbamic acid represented by formula (III):
• (wherein R1 and R2 are as defined above, and M denotes an alkali metal);
• and
• treating a phenol represented by formula (IV):
• Ar—OH (IV)
• (wherein Ar is as defined above) with a base in a solvent, adding thereto said alkali metal salt of N-(6-alkoxy-2-pyridyl)-N-alkyldithiocarbamic acid represented by formula (III) and a halomethane represented by formula (V):
• CH2XmYn (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).
