Te. Goodwin et al., Synthesis of C-13,H-2(3)-salmeterol: An analytical internal standard for pharmacokinetic studies, J LABEL C R, 43(1), 2000, pp. 65-75
A convenient synthesis of an isotopically-labelled version (C-13,H-2(3)) of
the long-acting beta(2)-adrenergic agonist, salmeterol, is described, star
ting from methyl salicylate, 1,6-dibromohexane and 4-phenyl-1-butanol. This
compound was designed as an analytical internal standard for mass spectrom
etric determination of salmeterol in pharmacokinetic studies.
