Abstract
A method for preparing a pyrazole of formula (I) in which R,R' and R″ have different meanings, characterised in that it involves reacting a sydnone of formula (II) in which R and R′ have the meanings already indicated, with an alkyne of formula (III) in which R″ has the meaning already indicated, in the presence of copper, to obtain a pyrazole compound of formula (I) that is then isolated and salified if desired.
