该中间体在本合成路线中的序号：(VI)The synthesis of a tritiated analogue of CP-93,318 is as follows: Treatment of the phenacyl bromide (V) with N-bromosuccinimide in methanol affords selectively bromo derivative (VI). Subsequent condensation of (VI) and thioamide (IV) (Scheme 1) provides tritiation precursor (VII). Exposure of (VII) to tritium in the presence of palladium on carbon (triethylamine/tetrahydrofuran) followed by purification using high-performance liquid chromatography provides [3H]-CP-93,318 (specific activity: 16.2 Ci/mmol, radiochemical purity greater than or equal to 98%).
