In the search of a potential backup for clopidogrel, we have initiated a HTS campaign designed to identify novel reversible P2Y12 antagonists. Starting from a hit with low micromolar binding activity, we report here the main steps of the optimization process leading to the identification of the preclinical candidate SAR216471. It is a potent, highly selective, and reversible P2Y12 receptor antagonist and by far the most potent inhibitor of ADP-induced platelet aggregation among the P2Y12 antagonists described in the literature. SAR216471 displays potent in vivo antiplatelet and antithrombotic activities and has the potential to differentiate from other antiplatelet agents.

A fast, one pot method with excellent yield has been developed for preparation of 1,4,5-trisubstituted pyrazoles. Treatment of β-dicarbonyl compounds with N,N-dimethylformamide dimethylacetal and hydrazine derivatives afforded immediately the desired pyrazoles under solvent-free conditions in the absence of catalyst.
