Reaction Steps
Combine 3-bromodibenzofuraan (0.5 g, 2.0 mmol) and tetrahydrofuran (30 ml). Cool to about −78° C. Add a solution of t-butyllithium, 1.6 M solution in hexane (2.2 ml, 3.0 mmol), then warn to about 0° C. for 10 min. Cool to about −78° C. and add dimethylformamide (0.5 ml, 5.9 mmol). Warm to room temperature, quench with water, and extract with dichloromethane. Combine the organic layers and wash sequentially with distilled water and brine and then dry (Na2SO4), filter, and concentrate to give a residue. Chromatograph the residue eluting with 8:2 hexane:EtOAc to give the title compound.
