automation of the RPA synthesis in modern synthesis apparatus. A high and stable radiofluorination yield achieved under the optimum fluorination conditions (Kryptofix 222 [K/K2.2.2.]+[18F–], DMF, 140 °C, 10 min) using 4,5-bis(butoxy)-2-nitrobenzaldehyde as a substrate (83±6%, the number of experiments was n = 15) makes this compound a precursor of choice for the radioactive synthesis.
