Novel thienopyrimidine derivatives which have excellent pharmacological uricosuric activity are prepared by reacting a thiophene derivative with cyanic acid or a salt thereof, urea or a reactive ester of carbamic acid. If desired, alkylated, halogenated or nitrated thienopyrimidine derivatives are produced by reacting thienopyrimidine derivatives with an alkylating, halogenating or nitrating agent, respectively.
通过将噻吩衍生物与氰酸或其盐、尿素或碳酸酰基的反应制备出具有出色药理利尿活性的新型噻吩并嘧啶衍生物。如果需要,可以通过将噻吩并嘧啶衍生物与烷基化、卤代化或硝化试剂反应,分别制备出烷基化、卤代化或硝化的噻吩并嘧啶衍生物。
