The chemicals and solvents used were of analytical grade and obtained from commercial suppliers (Scharlau (Barcelona, Spain), Merck (Darmstadt, Germany), and Fluka (St. Louis, MO, USA), and were used without further purification. Thin layer chromatography was performed using aluminum plates coated with silica gel 60F254 (Merck) in an appropriate eluent. The spots were visualized using ultraviolet irradiation. Melting points were recorded on Gallenkamp melting point apparatus (Sigma-Aldrich Chemie GmbH, Taufkirchen, Germany) and were uncorrected. 1H NMR spectra were recorded in CDCl3 and DMSO-d6 solvents on a Bruker Avance NMR (300 MHz) spectrometer (Karlsruhe, Germany) while 13C NMR spectra were recorded at 75 MHz. Chemical shifts are reported as δ values in parts per million (ppm) relative to tetramethylsilane as internal standard. Coupling constant (J) is given in Hertz. FTIR spectra were recorded on an Agilent Technologies Cary 630 FTIR (Santa Clara, CA, USA). Elemental analysis was performed on a LECO 630-200-200 TRUSPEC CHNS micro analyzer (St. Joseph, MI, USA) and the values observed were within ±0.4% of the calculated results. Compounds 2 and 3 were synthesized following the literature procedures [60 (link)].

Manufactured by Leco
Sourced in United States
The LECO 630-200-200 TruSpec CHNS microanalyzer is a laboratory instrument designed to determine the elemental composition of a sample, specifically the carbon, hydrogen, nitrogen, and sulfur content. It utilizes a combustion process to analyze the sample and provides accurate and reliable results.

All of the chemicals were purchased from Alpha
Aesar, Merck, and
Sigma-Aldrich through their local dealers and were used without further
purification. Solvents were purified by distillation. Melting points
were noted on a Gallenkamp melting point apparatus in an open-ended
capillary tube and were uncorrected. 1H NMR spectra (300
MHz) and 13C NMR spectra (75 MHz) were recorded in DMSO-d6 on a Brüker Avance NMR instrument.
Tetramethylsilane was taken as the internal standard, and chemical
shifts δ are reported in ppm. An Agilent Technologies Cary 630
FTIR spectrophotometer was used for IR spectral studies. Elemental
analyses were carried out in a LECO 630-200-200 TruSpec CHNS microanalyzer,
and the values are found to be within ±0.4% of the calculated
results.

All the chemicals were purchased from Merck and Sigma Aldrich through their indigenous suppliers and were used as received. Melting points were taken by open capillary method on Gallenkamp melting point apparatus and are uncorrected. 1H NMR spectra and 13C NMR spectra (300 and 75 MHz respectively) were recorded in DMSO-d6 on Brucker Avance NMR instrument. Chemical shifts δ are reported in ppm with reference to tetramethylsilane. FTIR spectral data was obtained on an Agilent Technologies Cary 630 FTIR spectrophotometer. Elemental analyses were investigated in LECO 630-200-200 TruSpec CHNS microanalyzer and the values are established to be within ± 0.4% of the calculated results. Compounds 2–4 and 6 were synthesized by procedures reported in literature.29,31 (link)
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
