Pyridine → HCID 86601875, compound

Participants

Reaction Steps

Dess-Martin periodinane (33.0 mg, 0.077 mmol) was added to a solution of 10b (62.0 mg, 0.077 mmol) and pyridine (31.0 μL, 0.386 mmol) in dichloromethane (1 mL) at room temperature. After 30 min, the reaction mixture was poured into saturated aqueous sodium bicarbonate, and extracted twice with ethyl acetate. The combined organic extracts were washed with water, brine, dried (MgSO4), filtered and concentrated in vacuo. Purification of the crude residue by flash chromatography on silica gel (gradient elution; 20-40% ethyl acetate/hexanes) afforded the title compound 10c.
