Kinetic studies on cyclization of 2-(2'-pyridyl)-cyclohexanone oxime hydrogensulfate and its derivatives bearing a substituent on pyridine ring to the corresponding 2,3-tetramethylenepyrazolopyridines were carried out in buffered solutions or in presence of NaHCO3.A two-stage mechanism of the cyclization was proposed.
