Participants

Reaction Steps

A 2.6 M hexane solution of n-BuLi was gradually added to a solution of the 1-(tert-butyl)-2-(methoxymethoxy)benzene (1013 g, 4.67 mol) and tetramethylethylenediamine (754 g, 6.5 ml) in dry ether while cooling on ice, and the mixture was stirred at room temperature for 3 hours. After recooling to 0° C., dimethylformamide (1000 ml, 14 mol) was gradually added and the mixture was stirred at room temperature for 1 hour. The reaction mixture was gradually added to ice water, extraction was performed with ethyl acetate, and the organic layer was washed with water and brine and then dried over anhydrous magnesium sulfate. The organic layer was concentrated under reduced pressure to yield a crude product of the title compound (1247 g) as a red oil.
