Other S-protecting groups for mercaptoacetyl triglycine have been reported. The S-benzyl derivative (X) was prepared by condensation of triglycine (I) with (benzylthio)acetyl chloride (IX). Alternatively, the S-benzamidomethyl compound (XII) was prepared as follows. Thioglycolic acid (V) was condensed with benzamidomethanol under acidic conditions to give S-(benzamidomethyl)thioglycolic acid (XI), which was then coupled to triglycine (I) using DCC/HOBt. Deprotection in the presence of 99Tc pertechnetate under the same conditions as above furnished the title Tc complex.
