Abstract

We describe the synthesis of 2-oxo-2H-chromen-7-yl 4-chlorobenzoate 3 in 88% yield by the O-acylation reaction of 7-hydroxy-2H-chromen-2-one 1 with 4-chlorobenzoyl chloride 2 in dichloromethane using a slight excess of triethylamine at 20 °C for 1 h. The ester 3 was completely characterized by mass spectrometry, IR, UV–Vis, 1D, and 2D NMR spectroscopy.
Keywords: 7-hydroxy-2H-chromen-2-one; O-acylation reaction; coumarin 7-hydroxy-2H-chromen-2-one; O-acylation reaction; coumarin
