Stable isotopically labelled (SIL) versions of Glimepiride 1 (10 steps, 11% overall yield), a blood glucose lowering drug, and Melagatran 13 (9 steps, 17% overall yield), an anticoagulant with similar uses to warfarin, were synthesized as internal standards for LCMS assays. Modifications of known routes (Weyer et al. , US Patent 4379785, Hocchst, 1983; Antonsson et al. , PCT International Application W09429336, 1994) to these compounds are examples of the introduction of stable isotopes via heterocyclic intermediates.
