Mode opératoire

4-Phenylazophenol (0.25 g, 1.26 mmoles) was dissolved in ether (5-10 mL) and triethylamine (0.26 mL) was added. Then propanoyl chloride (0.14 g 1.5 mmoles) in ether (1 mL) was added dropwise at room temperature. The mixture was stirred and reaction was rapidly completed. The reaction mixture was washed with water, dilute acid and brine and dried with magnesium sulfate. The solvent was evaporated to give 0.23 g (72%) of product. 1H NMR (CDCl3) δ=1.16 (3H, t, J=7.7), 2.40 (2H, q J=7.7), 7.25 (2H, m), 7.40-7.58 (3H, m), 7.88-8.0 (4H, m) ppm.
