摘要: A process for the preparation of anthelmintic compounds of the formula: ##STR1## wherein R.sup.1 is hydrogen or --COOR;R.sup.5 is C.sub.1 to C.sub.4 alkyl;R.sup.2 is halogen, alkyl, trifluoromethyl, alkoxy, aryloxy, or aralkoxy; andR.sup.4 is hydrogen, alkyl, cycloalkyl; alkenyl, alkynyl or aralkyl;or pharmaceutically acceptable salts thereof comprises subjecting a bis compound of the formula: ##STR2## to reduction to cleave the disulfide linkage and where R.sup.4 is other then hydrogen, subsequent reaction of the mercapto group. Intermediate compounds and a process for preparing same are also disclosed.
