Abstract

Procedure for obtaining tricyclo-oxa (thia) zolic derivatives of formula I, **(See formula)** where X is selected from the group consisting of an oxygen atom and a sulfur atom, it means alkyl of 1 to 4 carbon atoms, and R1 is selected from the group consisting of methyl, ethyl and β-hydroxyethyl radicals, characterized by that a compound of formula II is reacted, **(See formula)** wherein X and R1 have the meanings indicated above, and Z is selected from the group consisting of a chlorine atom and a bromine atom, with a 4-substituted piperazine compound of formula III, **(See formula)** wherein R2 has the above meaning, preferably by mixing the piperazine compound of formula III with the compound of formula II, with cooling, at a temperature of approx. -5º to + 15ºC, and then the mixture is allowed to heat to a maximum of approx. 30ºC.
