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.
3-(二甲基氨基)/ 3,3-双(甲硫基)-1-(取代的)丙-2-烯-1-酮与4-取代的5-氨基-1 H-吡唑之间的反应提供了新的吡唑[1]在结构上与扎来普隆有关的,5- α ]嘧啶。在双环结构的3、5和7位上引入的化学修饰揭示了治疗睡眠障碍的新有希望的候选者。
