The main suppliers of all chemicals (reagent grade) were Spectrochem, Alfa Aesar (India) and TCI. The silica gel 60 GF254 sheets (E. Merck, Germany) were used to run TLC (thin layer chromatography) and visualization was done using the UV light (254 nm). Normal-phase HPLC analysis was carried out using Hypersil BDS C18 150 mm x 4.6 × 3 µ. A Perkin-Elmer BX series FT-IR spectrometer was used for recording the IR spectra (KBr pellet). 1H & 13C NMR spectra were recorded using a 1H-Varian-Mercury-400 spectrometer. Chemical shift values are given in ppm (δ) using TMS as internal standard. A Mariner System 5304 MS spectrometer was used to record the ESI MS. The Q-TOF Micro mass spectrometer was used for recording the HRMS (high resolution mass spectra).
Bx series ft ir spectrometer
Manufactured by PerkinElmer
The BX series FT-IR spectrometer is a high-performance laboratory instrument designed for infrared spectroscopic analysis. It utilizes Fourier transform infrared (FT-IR) technology to capture and analyze infrared spectra of various samples. The core function of the BX series FT-IR spectrometer is to provide accurate and reliable infrared spectroscopic data for applications in research, quality control, and various other analytical fields.

All the melting points were determined on a Cintex melting point apparatus and are uncorrected. Analytical TLC was performed on Merck precoated 60 F254 silica gel plates. Visualization was done by exposing to iodine vapour. IR spectra (KBr pellet) were recorded on a PerkinElmer BX series FT-IR spectrometer. 1H NMR spectra were recorded on a Varian Gemini 300 MHz spectrometer. 13C NMR spectra were recorded on a Bruker 75 MHz spectrometer. Chemical shift values are given in ppm (δ) with tetramethylsilane as an internal standard. Mass spectral measurements were carried out by the EI method on a Joel JMC-300 spectrometer at 70 eV. The synthesis of compounds 5a-j was accomplished by synthetic route shown in scheme 1 .
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.
