A modified alc.-enhanced 18F-fluorodeboronation has been developed for the radiosyntheses of [18F]JNJ-46356479 and [18F]FITM. Unlike the [18F]KF/K222 approach, this method tolerates the presence of sensitive heterocycles in Bpin precursors 4 and 8 allowing a one-step 18F-fluorodeboronation on the fully automated TRACERlab FXFN platform. This study involved multiple reactions and reactants, such as 4-(6-Chloropyrimidin-4-yl)-N-methylthiazol-2-amine (cas: 932738-80-2COA of Formula: C8H7ClN4S).
4-(6-Chloropyrimidin-4-yl)-N-methylthiazol-2-amine (cas: 932738-80-2) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Thiazole is a versatile building block for the construction and lead generation of new drug discoveries. Numerous diazole-based compounds are in clinical use as anticancer, antileukemic, antiinflammatory, antiviral, antifungal, antirheumatic, immunomodulator, and antiparasitic agents.COA of Formula: C8H7ClN4S
