All solvents and reagents purchased from Sigma or Merck companies were used as received without further purification. Solvent system used throughout experimental work for running TLC was ethyl acetate and hexane mixture (in suitable proportion) in order to monitor the progress of reactions. Melting points were uncorrected and determined in open capillary tubes on a Precision Buchi B530 (Flawil, Switzerland) melting point apparatus containing silicon oil. IR spectra of the synthesized compounds were recorded using FTIR spectrophotometer (Shimadzu IR Prestige 21, India). 1H NMR spectra were recorded on a Bruker DPX-400 spectrometer (Bruker India Scientific Pvt. Ltd., Mumbai) using TMS as an internal standard (chemical shifts in δ). ESMS were recorded on MICROMASS Quattro-II LCMS system (Waters Corporation, Milford, USA).
Micromass quattro 2 lcms system
Manufactured by Waters Corporation
Sourced in United States
The MICROMASS Quattro-II LCMS system is a liquid chromatography-mass spectrometry (LC-MS) instrument designed for analytical applications. It combines liquid chromatography for sample separation and mass spectrometry for detection and identification of compounds. The system is capable of performing high-sensitivity and high-resolution mass analysis.

All reagents and solvents purchased from Sigma or SD fine companies were used as received without further purification. The progress of reaction was monitored by thin layer chromatography (TLC) using ethyl acetate and hexane (in suitable proportion) as mobile phase and silica as stationary phase. Melting points were uncorrected and determined in open capillary tubes on a Precision Buchi B530 (Flawil, Switzerland) melting point apparatus containing silicon oil. The IR spectra of the synthesized compounds were recorded using FTIR spectrophotometer (Shimadzu IR Prestige 21, Shimadzu, Mumbai, India). 1 H and 13 C NMR spectra were recorded on Bruker DPX-400 spectrometer (Bruker India Scientific Pvt. Ltd., Mumbai, India) using TMS as an internal standard (chemical shifts δ in ppm, J values in Hz). Elemental analysis was performed on Vario EL III M/s Elementar C, H, N, and S analyzer. ESI-MS were recorded on MICROMASS Quattro-II LCMS system (Waters Corporation, Milford, USA).

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.
