Reaction Steps
A suspension of 65% sodium hydride (9.3 g)/dimethylformamide (100 ml) was ice-cooled, followed by the addition of 4-iodophenol (50.5 g)/dimethylformamide (200 ml) solution, and the mixture was stirred for 3 hr. To the mixture solution was added (1,3-dioxolan-2-yl)methylbromide (46.0 g), and the mixture was reacted at 60° C. for 1 day. The reaction solution was poured into water, and extracted with ethyl acetate. The resulting organic layer was washed with water and brine, and then dried (over magnesium sulfate). The solvent was removed, and the resulting residue was purified by NH silica gel column chromatography (chloroform), and then recrystallized from ethyl acetate/hexane, to give 32.7 g of the title compound as pale yellow prisms.
