2-(3,5-Dimethyl-1H-pyrazol-1-yl)thiazolo[4,5-b]pyridine

Round 1

Reviewer 1 Report

The same method of synthesis and x-ray crystallography studies of the title compound have already been published in Z. Kristallogr. NCS 229 (2014) 145-146 / DOI 10.1515/ncrs-2014-0081. That is way the material presented by the authors cannot be published in Molbank as new material.

Thank you very much for your comments on our manuscript.

Reviewer 2 Report

The authors report preparation and characterization of a new heterocyclic compound containing pyridine, thiazole and pyrazole rings. The target compound 1 was synthesized in good yield by reaction of a hydrazine with a diketone. This reaction has a potential for synthesis of pyrazole derivatives with various substituents. The product was ambiguously identified by 1H and 13C NMR as well as X-ray diffraction study. This referee accepts the publication in this journal after some revisions as listed below.

In general information, a supplier of 1-(thiazolo[4,5-b]pyridin-2-yl)hydrazine should be given. In section 3.2, the signal at 6.08 ppm in the 1H NMR spectrum is lacking.

Reviewer 3 Report

The novelty of this manuscript is very small.
