Participants

Reaction Steps

To a solution of 1-(cyclopropylmethoxy)-2,3-difluorobenzene (19.0 g) in THF (200 mL) was added 1.6 M n-butyllithium hexane solution (64.5 mL) at −78° C., and the mixture was stirred at the same temperature for 1 hr. To the reaction mixture was added dry ice, and the mixture was allowed to warm to room temperature, and stirred for 15 min. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution, and the aqueous layer was washed with diethyl ether, and acidified with 6N hydrochloric acid. This mixture was extracted with ethyl acetate, and the extract was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the obtained solid was washed with diethyl ether to give the title compound was obtained.
