Participants

Reaction Steps

Methyl 3-(4-methoxyphenyl)-3-methylbutanoate (475 mg, 2.137 mmol) was dissolved in ethanol (20 mL). Iodine (542 mg, 2.137 mmol) and silver sulfate (666 mg, 2.137 mmol) were added and the reaction was stirred vigorously at room temperature, protected from light, for 1 hr. The reaction was then diluted with ethyl acetate (40 mL) and filtered. The filtrate was washed with sodium bisulfite (2×50 mL), water (50 mL), and brine (50 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated. The residue was purified by flash chromatography on silica gel with 0 to 50% ethyl acetate/hexanes to afford methyl 3-(3-iodo-4-methoxyphenyl)-3-methylbutanoate. 1H NMR (CDCl3, 500 MHz) δ 7.73 (d, J=2.5 Hz, 1H), 7.29 (dd, J=8.6, 2.5 Hz, 1H), 6.75 (d, J=8.4 Hz, 1H), 3.86 (s, 3H), 3.55 (s, 3H), 2.57 (s, 2H), 1.41 (s, 6H).
