该中间体在本合成路线中的序号：(IV)Palladium-catalyzed coupling of 5-bromopyrimidine (I) with ethyl acrylate (II) afforded pyrimidinyl acrylate (III), which was hydrogenated over Pd/C to give (IV). Claisen condensation of (IV) with ethyl formate furnished oxoester (V). This was then cyclized with thiourea (VI) to produce the intermediate thiouracil (VII).
