Participants

Reaction Steps

After adding 1.05 g of molecular sieves 4 A, 1.00 g (6.70 mol) of p-formylphenylboric acid, 605 mg (3.30 mol) of copper (II) acetate and 2.32 ml (16.6 mol) of triethylamine to a solution of 700 mg (3.30 mmol) of the obtained phenol compound in methylene chloride (30 ml), the mixture was stirred at room temperature overnight under a oxygen atmosphere. The reaction mixture was filtered and then concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane:acetic acid ethyl ester=5:1) to obtain 593 mg of 3-(4-formylphenoxy)-5-isopropoxybenzoic acid methyl ester (yield: 57%) as a colorless oil.
