The present invention relates to a process using Grignard reagents for providing thio-triazolo group-containing compounds.
Claims10
A process for preparing a compound (IIIa)
- comprising
- (i) reacting a compound of formula (IV)
- with a Grignard reagent R1MgQ (V), wherein:
- R is an organic group;
- Q is R1 or X, wherein X is halogen;
- and
- R1 is (C1-C10)-alkyl, (C2-C10)-alkenyl, (C2-C10)-alkynyl, (C3-C8)-cycloalkyl or (C6-C10)-aryl, wherein the aryl is unsubstituted or substituted by one, two or three groups independently selected from the group consisting of halogen and (C1-C4)-alkyl.
