The α2-adrenergic receptor antagonist atipamezole has been labelled with carbon-11 using [11C]formaldehyde and 2-ethyl-2-oxoacetylindane. Various routes are proposed for the synthesis of the latter: oxidation of 2-acetyl-2-ethylindane, hydrolysis of 2-diethoxy-2-indane and oxidation of 2-diazoacetyl-2-ethylindane. The average radiochemical yield of [11C]atipamezole was 24% based on [11C]formaldehyde, and the synthesis time, including HPLC purification and formulation, was 45 min.
