tert-Butanol → Tert-butyl 3-iodo-2-methoxybenzoate

Participants

Reaction Steps

To a cooled (−5° C.) solution of tert-butanol (12.87 mL, 30 mmol) in THF (30 mL) was added, dropwise, BuLi (12.0 mL, 2.5 M in hexanes, 30 mmol). On complete addition, the solution was stirred for 20 minutes. To this solution is added a solution of 3-Iodo-2-methoxy-benzoyl Chloride (8.8 g, 29.8 mmol) in THF (12 mL). On complete addition, the cold bath was removed and stirring continued for 1.5 hours. This solution was diluted with ethyl acetate, washed with water and brine, dried over magnesium sulfate and concentrated. The residue was purified by silica chromatography (50 g silica; eluted with 0-20% ethyl acetate in hexanes) to give the title compound as an oil.
