Pentane → HCID 19437716, compound

Participants

Reaction Steps

To a solution of the dibenzofuran 10 (995 mg, 2.5 mmol) in anhydrous THF (25 mL) at -78° C. under a nitrogen atmosphere was added a 1.7M t-butyllithium in pentane solution (3.0 mL, 5.1 mmol). The resulting yellow solution was stirred for 100 min., then trimethyltin chloride (548 mg, 2.75 mmol) was added as a solid. The mixture was allowed to warm to ambient temperature and then stirred for 3 hours. The reaction mixture was then poured into ether and the organic solution was washed with water (3 times) and then with brine. The organic solution was then dried with magnesium sulfate, filtered and concentrated under vacuum. Flash chromatography of the residue (silica gel, 10% methylene chloride in hexanes) provided 815 mg of the stannane 316 (68% yield) as a crystalline solid.
