A novel chelator of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) functionalized by adamantane was synthesized by nucleophilic substituted reaction of 1,4,7-Tris(tert-butoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane (5) and N-(adamantan-1-yl) bromoacetamide (2). The intermediates and target compound (7) were characterized by fourier transform infrared spectroscopy (FT-IR), 1H nuclear magnetic resonance (NMR), 13C NMR, atmospheric-pressure ionization electrospray mass spectrometry (API–ES–MS), and elemental analysis.
