  Reported herein is a general strategy for the photochemical cross-coupling between N-amidopyridinium salts and various alkyl bro-mides under photocatalyst-free conditions, granting facile access to various C4-alkylated pyridines. This approach exploits the intri-guing photochemical activity of electron donor-acceptor (EDA) complexes between N-amidopyridinium salts and bromide, which provides a photoactive

  A series of 3-(2,4-dichlorophenyl)-N-alkyl-N-fluoroalkyl-2,5-dimethylpyrazolo[1,5-a]pyrimidin-7-amines were synthesized and evaluated as potential positron emission tomography (PET) tracers for the corticotropin-releasing factor type-1 (CRF1) receptor. Compounds 27, 28, 29, and 30 all displayed high binding affinity (<= 1.2 nM) to the CRF1 receptor when assessed by in vitro competition binding assays at 23 degrees C, whereas a decrease in affinity (>= 10-fold) was observed with compound 26. The logP(7.4) values of [F-18]26-[F-18] 29 were in the range of similar to 2.2-2.8 and microPET evaluation of [F-18]26-[F-18] 29 in an anesthetized male cynomolgus monkey demonstrated brain penetrance, but specific binding was not sufficient enough to differentiate regions of high CRF1 receptor density from regions of low CRF1 receptor density. Radioactivity uptake in the skull, and sphenoid bone and/or sphenoid sinus during studies with [F-18]28, [F-18]28-d(8), and [F-18]29 was attributed to a combination of [F-18]fluoride generated by metabolic defluorination of the radiotracer and binding of intact radiotracer to CRF1 receptors expressed on mast cells in the bone marrow. Uptake of [F-18]26 and [F-18]27 in the skull and sphenoid region was rapid but then steadily washed out which suggests that this behavior was the result of binding to CRF1 receptors expressed on mast cells in the bone marrow with no contribution from [F-18]fluoride.
