Title:
METHOD FOR PRODUCING PYRAZOLES, PYRAZOLE-TYPE DERIVATIVES AND APPLICATIONS THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/122407
Kind Code:
A3
Abstract:
A method for preparing a pyrazole of formula (I), characterised in that it involves reacting a sydnone of formula (II) with an alkyne of formula (III) in the presence of copper, in order to obtain a pyrazole compound of formula that is then isolated and salified if desired.
