Fig. 2From: Improved synthesis of 6-bromo-7-[11C]methylpurine for clinical useTypical chromatograms of semi-preparative HPLC for the reaction mixture. The peaks of N7 and N9 show [11C]7m6BP and [11C]9m6BP, respectively. ACT, DMSO, THF, 2-MeTHF, 1,4-DO, and AcOEt were used as reaction solventsBack to article page
