Two methods were developed for the synthesis of [2-11C]5,5-dimethyl-2,4-oxazolidinedione ([2-11C]DMO) for use with positron emission tomography to measure regional cerebral tissue pH in vivo in man. In both methods, A and B, [2-11C]dimethyl carbonate (DMC) was prepared from [11C]phosgene and excess of sodium methoxide in methanol containing 2… (More)
