Abstract
Process for the obtaining of compounds of halofanoilpiperazina, of formula (I), where r is lower or phenyl rent; r and r are hydrogen or lower rent; and r can be one of various types of radicals. It consists in the reaction of a compound of halofanoilpiperazine of formula (II) with a halogen compound of formula x-r, where x is a halogen atomus and the other symbols have the same meaning as in formula (I). The reaction is carried out in an inert solution, in the presence of a base, at temperatures between -20 c and that of bleaching of the solvent. These compounds have pharmacological applications for their analgesic activity. (Machine-translation by Google Translate, not legally binding)
