the direct functionalization of pyridines. These reactions occur under mild conditions and exhibit broad functional group tolerance, enabling the late-stage functionalization of drug-like molecules. The reagent can be easily prepared on large scale from inexpensive reagents, and reacts in the title reaction with acetonitrile, sodiumchloride, and sodium methanesulfonate as the sole byproducts.

2-Benzyl-4-(4-pyridyl)thiazoles and derivatives thereof have been made from converting a benzyl cyanide to the corresponding thioamide followed by condensation with a 4-bromoacetylpyridine. The thiazole derivatives are found to be effective immunoregulants.

selective modification of nitrogen heteroaromatics enables the development of new chemical tools and accelerates drug discovery. While methods that focus on expanding or contracting the skeletal structures of heteroaromatics are emerging, methods for the direct exchange of single core atoms remain limited. Here, we present a method for 14N → 15N isotopic exchange for several aromatic nitrogen heterocycles

thereof are disclosed wherein dently are, e.g., hydrogen; halo; RaRb wherein R, and C1-6 alkyl single or a double bond: for double bond-connection, R2 can be, e.g., =0 or =S; for single-bond connection, there can be one or two sets of R2 and each R2 independently is R; R3 is Ra, halo or haloloweralkyl; n is 1 to 4; m is 1 to 5; and q is 0 or 1. These compounds have been made from converting a benzyl cyanide to the corresponding thioamide followed by condensation with a 4-bromoacetylpyridine. The thiazole derivatives are found to be effective immunoregulants.
