YieldReaction ConditionsOperation in experiment
78% To a well-stirred suspension of 3 g (9.2 mmol) of <strong>[10016-52-1]2,8-dibromodibenzofuran</strong> (1) in 45 ml of dry ether under a nitrogenatmosphere at -78 °C in a dry ice/acetone bath was added 8.1 ml (20.24 mmol) of a 2.5 M solution of n-butyl lithium in hexane. The resulting suspension was allowed to warm to room temperature and was stirred for 2 h. Then it was added 2.14 ml (27.6 mmol) of DMF under a nitrogen atmosphere at -78 °C in a dry ice/acetone bath. The mixture was allowed to gradually warm to room temperature for 8 h. After addition 10percent aqueous hydrochloric acidsolution, the precipitated solid was collected by filtration, washed with water, dried. The product was crystallized from dry ether and 1.6 g of white solid was obtained. The yield was 78percent; m.p. 192-194 °C
