摘要

Process for obtaining new substituted phenylamino-1,3-diazacyclopentene- (2) of the general formula ** (See formula) ** -where Z represents the residue of 2,6-dichlorophenyl, 3,5-dichlorophenyl, 3,4-dichlorophenyl, 2,6-dibromophenyl, 2-fluoro-4-chlorophenyl, 2-trifluoromethyl-phenyl, 2-chloro-6 -methylphenyl, 2-methyl-4-chloroennyl, 2-chloro-4-methylphenyl, 2-chloro-4-ethylphenyl- 2-chloro-6-ethylphenyl, 2-chloro-4-tert.butylphenyl, 2,6-dichloro -4-methylphenyl, 2,4-dichloro-6-methylphenyl, 2,4-dimethyl-6-chlorophenyl, 2,6-dimethyl-4-chlorophenyl or 2,4,6-trimethylphenyl- as well as its acid salts of physiologically harmless addition, characterized by a) reacting with ethylenediamine, optionally using a suitable solvent, an isothiouronium salt of the formula ** (See formula) ** where Z has the indicated meaning, R 'represents a lower alkyl moiety and X represents an acid moiety, or b) being transformed with ethylenediamine a thiourea derivative of the general formula ** (See formula) ** where Z has the indicated meaning, or c) to undergo pyrolysis a compound of the formula ** (See formula) ** where Z has the indicated meaning and Y = S or = 0, and eventually the compounds of the formula I thus obtained in their physiologically harmless acid addition salts can be converted in a conventional manner.
