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.
