Synthesis and molecular structure of 1-(Pyrimidin-2-yl)-2-(4-aryl-1,3- thiazol-2-yl)hydrazines
Reactions of some 2-hydrazinopyrimidine hydrochlorides with potassium thiocyanate gave 1-(pyrimidin- 2-yl)thiosemicarbazides which underwent Hantzsch condensation with aryl chloromethyl ketones to produce 1-(pyrimidin-2-yl)-2-(4- aryl-1,3-thiazol-2-yl)hydrazine hydrochlorides. The protonation was accompanied by mutually dependent tautomeric rearrangements of heterocyclic fragments. Pleiades Publishing, Ltd., 2011.
