As part of our ongoing investigation into the imaging of angiogenic processes, a small library of eight vascular endothelial growth factor receptor-2 (VEGFR-2)/platelet-derived growth factor receptor β dual inhibitors based on the N-phenyl-N′-4-(4-quinolyloxy)-phenyl-urea was labelled with 11C (β+, t1/2 = 20.4 min) in the urea carbonyl position via rhodium-mediated carbonylative cross-coupling of an aryl azide and different anilines. The decay-corrected radiochemical yields of the isolated products were in the range of 38-81% calculated from [ 11C]carbon monoxide. Starting with 10.7±0.5 GBq of [ 11C]carbon monoxide, 1-[4-(6,7-dimethoxy-quinolin-4-yloxy)-3-fluoro- phenyl]-3-(4-fluoro-phenyl)-[11C]-urea (2.1 GBq) was isolated after total reaction time of 45 min with a specific activity of 92±4 GBq μmol-1.
