The synthesis of the potent dual-acting PPARα and PPARγ agonist NNC 61-4655 labelled with tritium and carbon-14 is reported. Tritium labelled NNC 61-4655 was obtained in three steps with introduction of tritium through catalytic tritium-halogen exchange of an aryl bromide precursor. This provided [3H]NNC 61-4655 in 39% overall radiochemical yield with a specific activity of 49 Ci/mmol. Carbon-14 labelled NNC 61-4655 was obtained in five steps starting from bromo[1-14C]acetic acid. The synthetic sequence, which included a Horner–Wadsworth–Emmons olefination and a Mitsunobu alkylation, provided [14C]NNC 61-4655 in 33% overall radiochemical yield with a specific activity of 57.4 mCi/mmol.
