    Abstract: The present invention is dealing with compounds of the formula: ##STR1## and pharmaceutically acceptable salts thereof, in which n and m represent the number 1 or 2, X and Y hydrogen, alkyl (1-4 C), alkoxy (1-4 C), hydroxy, halogen, hydroxymethyl, trifluoromethyl, acyl (1-4 C), acyloxy (1-4 C) or the group NR.sub.x R.sub.y, in which R.sub.x and R.sub.y represent hydrogen, alkyl (1-4 C) or a sulphonyl group and R represents the group ##STR2## in which R.sub.1 and R.sub.2 represent hydrogen, alkyl (1-4 C), hydroxy, alkoxy (1-4 C), phenylalkoxy (7-10 C), acyloxy, amino or mono or dialkyl (1-4 C) amino, having potent platelet aggregation inhibiting properties.

  • Patent number: 4456769
    Abstract: A new one-step process for the preparation of hydrazidines of the general formula ##STR1## in which R represents an optionally substituted alkyl group, an optionally substituted cycloalkyl group, an optionally substituted aryl group or an optionally substituted aralkyl group,or their acid addition salts, in high yield comprises reacting iminoalkyl ethers of the general formula ##STR2## in which R has the abovementioned meaning andR.sup.1 represents an optionally substituted alkyl group or an optionally substituted cycloalkyl group,or their acid addition salts, with hydrazine in solvents under reduced pressure and at temperatures between -80.degree. and +100.degree. C., the reaction being effected in the presence of water present in the solvent and/or in the hydrazine by employing it as hydrazine hydrate. The hydrazidines of formula (I) and their salts are valuable intermediates in heterocyclic chemistry, for example for the synthesis of herbicidally active as-triazinones.
