The facile synthesis of a pyrimidinyl sulfonamide (N,N,N,6-tetramethyl-2- (4-nitrophenylsulfonamido)pyrimidin-4-ammonium chloride) as a PET tracer precursor

We synthesized the novel sulfonamide derivative, N,N,N,6-tetramethyl-2-(4- nitrophenylsulfonamido)pyrimidin-4-ammonium chloride (7), for use as a precursor in [18F]fluoride chemistry. For this, 4-nitrobenzenesulfonyl guanidine was used as the s
