Reaction Steps

To the suspension of the acid chloride of 6-acetoxymethyl-2-oxo-2H-1-benzopyran-3-carboxylic acid (4 mmol) obtained according to Pochet et al. (Bioorg. Med. Chem. 2000, 8, 1489) in anhydrous dioxane (10 mL) was added 2-iodophenol (5 mmol) and pyridine (0.4 mL). After 12 h stirring at room temperature, the solvent was evapotated under vacuum and the residue was suspended in methanol.
