Research on Heterocyclic Compounds, XXXV [1]. Synthesis of 2-Phenylimidazo[1,2-a]-pyrazine-3-acetates

Avallone,Rimoli,Abignente

, p. 947 - 953 (2007/10/03)

Prompted by the remarkable pharmacological activity shown by the corresponding carboxylic acids and other analogues, a series of 2-phenylimidazo[1,2-a]pyrazine-3-acetic acids has been prepared. A multi-step method similar to a synthetic procedure used to obtain Zolpidem, an imidazo[1,2-a]pyridine with hypnotic properties has been developed.
