Tritiation of the cannabinoid receptor antagonist SR144528 involving lithium aluminum tritide reduction; assessment of the kinetic isotope effect by 3H-NMR

The cannabinoid receptor antagonist SR144528 was synthesized by an approach that enabled the incorporation of high specific activity tritium label while circumventing the lability of the target compound to catalytic hydrogenation. Lithium aluminum tritide
