## Abstract A selective and potent analogue of the anti‐herpes agent acyclovir has been labelled with ^11^C in good yield and at high specific activities. 1‐[^11^C]‐Methyl‐9‐(2‐hydroxyethoxy)methyl)guanine may be useful for detecting HSV encephalitis using positron emission tomography.

Abstract
In this paper we present the radiochemical synthesis of the novel compound [N‐methyl‐^11^C]methylene blue. The synthesis of [N‐methyl‐^11^C]methylene blue was accomplished by means of ^11^C‐methylation of commercially available Azure B using [^11^C]methyl trifluoromethanesulfonate ([^11^C]methyl triflate). Following purification [N‐methyl‐^11^C]methylene blue was obtained with a radiochemical purity greater than 97% in a 4–6% decay corrected radiochemical yield. The synthesis was completed in an average of 35 min following the end of bombardment. Copyright © 2003 John Wiley & Sons, Ltd.
