-1- ABSTRACT The present invention is directed to a process for producing a 2-iminothiazoline derivative of the general formula [II], characterized in that a thiourea derivative of the general formula [I] is treated with an acid. The invention is further directed to a process for producing an N-substituted N-aryl-cyanamide derivative of the general formula [VI], characterized in that an N-arylcyanamide derivative of the general formula [IV] is reacted with an allyl halide derivative of the general formula [V] in an aprotic polar solvent in the presence of an iodide and an alkali metal carbonate; and a process for producing an N-substituted N-arylthiourea derivative of the general formula [VII], characterized in that an N-substituted N-arylcyanamide derivative of the general formula [VI] obtained as described above is further reacted with a chemical species which generates a sulfide ion or a hydrogensulfide ion. The 2-iminothiazoline derivatives of the present invention are useful as intermediates in the production of medicaments and agricultural chemicals.
