(Chemical Equation Presented) The reaction between 3-(dimethylamino)/3,3- bis(methylthio)-1-(substituted)prop-2-en-1-ones and 4-substituted-5-amino-1H- pyrazoles afforded new pyrazole[1,5-a]pyrimidines structurally related to Zaleplon. The chemical modifications introduced at the 3-, 5-, and 7-positions of the bicyclic structure revealed new promising candidates for the treatment of sleep disorders.
