Participants

Reaction Steps

To a mixture of diethyl (3-methoxy-4-methoxycarbonylbenzyl)phosphonate (1.28 g) and acetone (1.5 ml) in N,N-dimethylformamide (5 ml) was added 60% sodium hydride-oil dispersion (162 mg). The reaction mixture was stirred at room temperature for 14 hours and then poured into ice-cooled 10% citric acid. The mixture was extracted with ether and the organic layer was washed with water and brine, dried over magnesium sulfate and concentrated. The residue was chromatographed on silica gel column eluting with a mixture of n-hexane and ethyl acetate (85:15) to give methyl 2-methoxy-4-(2-methyl-1propenyl)benzoate (184 mg) as an oil.
