Participants

Reaction Steps

To a solution of 2-(2-fluoropyridin-4-yl)-1-phenylethanone (450 mg, 2.1 mmol) in dry THF (10 mL) at 0° C. was added a solution of sodium bis(trimethylsilyl)amide (2.1 mL, 1M). After 10 min. 1-bromopinacolone (309 μL, 2.3 mmol) was added dropwise and the solution stirred for 2 h. The solution was poured into ethyl acetate (25 mL) and H2O (25 mL) and the layers allowed to separate. The organic layer was collected and the aqueous layer extracted with ethyl acetate (30 mL). The combined organic layers were washed with H2O and brine, dried (MgSO4) and concentrated. The product was purified by flash chromatography using EtOAc-Pet. spirit (20:80) as eluant to give the pure product as a pale yellow oil (574 mg, 87%).
