## Abstract The promising __β__‐amyloid PET imaging agent, [^11^C]‐6‐OH‐BTA‐1, has been radiolabelled in one step using [^11^C]‐methyl triflate. No protection of the 6‐hydroxy group is required, greatly simplifying the synthetic method. The reaction may be carried out in solution or by the captive

Abstract
The rapid, simple and high‐yield synthesis of the extraordinarily reactive ^11^C‐methylating agent, [^11^C]methyl nona‐fluorobutyl‐1‐sulfonate ([^11^C]MeONf), and its use in the synthesis of the promising β‐amyloid imaging agent, [^11^C]‐6‐OH‐BTA‐1, is reported. In terms of radioactive methylation yields, [^11^C]MeONf seems to surpass [^11^C]methyl trifluoromethansulfonate ([^11^C]MeOTf) as a methylating agent in this particular case giving the ^11^C‐labelled compound in high‐preparative radiochemical yields between 27 and 29% EOS with a minimum formation of radioactive by‐products.
