4-[(3,5-Dimethyl-1H-pyrazol-1-yl)methyl]-4-methyl-2-phenyl-4,5-dihydrooxazole

Round  1

Reviewer 1 Report

As the authors start from a compound having an asymmetrical carbon, this should appear in the nomenclature of the product.

English improvement is especially to make in lines 91-98: was left etc
In line 93 what is one?
Are the crystals white or colorless? There is always a difficulty when giving the color of crystals.

Author Response

- We did not check the absolute configuration of the product (1); considered as a starting product.

- In line 93: ... and then we add drop by drop for 20 minutes  ...

- The product is obtained as white solid in powder form.

Reviewer 2 Report

The preparative subject of the ms is correct.

However, the paper is full of linguistic problems. A few are mentioned below:

“in the reflux of DMSO”(page 1, line 17)

“are very important class of molecules” (page 1, line 23)

“we described in this present short note” (page 1, line 30)

“with a pyrazole nucleus” (page 1, line 39)

“in the first time” (page 1, line 41)

“proves to be necessary” (page 2, line 45)

“corresponding successively to the Me groups” (page 2, line 52)

“NMR spectrum (Figure 2) shows too that” (page 2, line 67)

“in perfect agreement with the high electronegativity of the oxygen atom than the nitrogen atom.” (page 2, line 71)

“are shown in table below” (page 2, line 72)

“the obtained organic layer is washed” (page 4, line 96)

Other issues:

In the abstract, please do not mention the structure proving, as it is trivial.

On page 2, NMR shifts are given as 4.069, 4.042 and 4.939. The accuracy is excessive!

In the experimental, please give also g or mL quantities beside the molar quantities.

In Conclusion: instead of “synthesized compounds”, please write “product”.

In overall, after the refinement of the usage of English by a native English speaker, some minor revisions are recommended.

 Author Response

- In the abstract, we did not mention the structure proving.

- On page 2, we have changed in an approximate way the NMR shifts.

- In the experimental, we added the quantities in g.

- In conclusion, we have changed ''synthesized compound'' by ''product''.
