6 A new series of benzooxazoles have been designed and synthesised ( Scheme 1). Chemicals STI571 price and solvents were reagent grade and used without further purification. Melting points were determined on a capillary melting point apparatus and are uncorrected. The 1H NMR spectra were recorded in the indicated solvent on a Varian 400 MHz spectrometer
with TMS as internal standard. All chemical shifts (δ) were reported in ppm from internal TMS. Mass spectra were measured on a Jeol JMS D-300 spectrometer. Infrared spectra were recorded in KBr on Brucher-IFS-66 FTIR spectrophotometer. The homogeneity of the compounds PLX3397 was checked using precoated TLC plates (E.Merk Kieselgel 60 F254). 2-Iodoaniline (1) (0.1 mmol), oxthiocyanate (0.15 mmol) and a few drops of DMF and FeCl3 were irradiated under microwave for 2–3 min. After the completion of reaction, it was poured
onto ice and product was extracted from ethyl acetate.
