摘要：There is disclosed a process for producing an iminothiazoline derivative of thegeneral formula: ##STR1## wherein R.sup.1 is halogen, halo(lower)alkyl,

halo(lower)alkoxy or halo(lower)alkylthio; R.sup.2 is hydrogen or halogen; and R.sup.4 ishydrogen or lower alkyl. This compound (I) can be obtained by cyclization of a thioureaderivative of the general formula: ##STR2## wherein R.sup.1, R.sup.2 and R.sup.4 are eachthe same as defined above, and R.sup.3 is hydrogen or (lower) alkylcarbonyl optionallysubstituted with at least one substituent selected from the group consisting of halogen,lower alkyl and lower alkoxy.
