57 2-Benzyl-4-(A-pyridyl)thiazoles and derivatives thereof of formula
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.
