Abstract
An useful18F labelled intermediate 4-[18F] fluorobenzaldehyde is prepared from trimethylammoniumbenzaldehyde triflate,and the labeling procedure is optimized by verti-cal-method.Under the optimized conditions,the synthesis time is 45 min,labeling yields is 62.1%,the radiochemical yield is 56.5%(decay-corrected) and the radiochemical purity is greater than 95% after purified.
