There is disclosed a process of 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. Also disclosed are a process of producing an N-substituted N-arylcyanamide 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 of 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 sulfide ion or hydrogensulfide ion.
