Abstract
Process for obtaining heterocyclic guanidine derivatives of formula I ** (See formula) ** where one of the radicals R1 and R2 means hydrogen or lower alkyl and the other lower alkyl, where R1 and R2, on the same carbon atom, may contain a total of at most 2 carbon atoms, R3 and R4 each meaning hydrogen or methyl and Y represents a direct bond and Z a radical NH2 or Y a radical NH and Z hydrogen, and their acid addition salts, characterized in that a hydrazine derivative of formula II ** (See formula) ** where R1 and R2 have the meaning above, is reacted with a compound of formula III ** (See formula) ** where R 4 has the meaning indicated above and either R 3 agrees with R 3 of the definition above and Z means an alkylthio residue or a 1-pyrazolyl radical mono- or di-substituted by lower alkyl or aryl, or Z and R'3 together form a third bond between the carbon atom and the nitrogen atom, in the presence of an equivalent of an acid, the base obtained is released from the salt obtained and, if desired, it is treated with an inorganic or organic acid.
