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.
制备出具有优异药理尿酸排泄活性的新型噻唑嘧啶衍生物,方法是将噻吩衍生物与氰酸或其盐、脲或氨基甲酸酯反应。如果需要,可以通过将噻唑嘧啶衍生物与烷基化、卤代或硝化试剂分别反应来生产烷基化、卤代或硝化的噻唑嘧啶衍生物。
