[11C]CGS 25966, a novel radiolabeled matrix metalloproteinase (MMP) inhibitor, has been synthesized for evaluation as new potential positron emission tomography (PET) tumor imaging agent. The precursor was labeled by [11C]methyl triflate through O-[11C]methylation method at the hydroxyl position of phenol under basic conditions and isolated by HPLC purification to produce pure target compound in 15–25% radiochemical yield, based on 11CO2, decay corrected to end of bombardment.
