Abstract

Melting points were measured on an Electerothermal 9100 apparatus and are uncorrected. Infrared spectra (n cm-1) were recorded on Shimadzu IR-470, using KBr disks. 1H NMR spectra were recorded on DRX-500 MHz NMR Spectrometer at 293 K in CDCl3. Spectra were internally referenced to TMS. Peaks are reported in ppm downfield of TMS. The NMR and IR spectra of the products were in agreement with earlier data. Microwave synthesizer; (Questron Technologies ...
