Triphenylphosphine → HCID 178513313, compound

Participants

Reaction Steps

To a solution of the azide (11-4) of Example 52 in THF/water (80 ml/5 ml) (7.8 g, 40.6 mmol) was added triphenylphosphine (12.8 g, 48.72 mmol). The reaction mixture was stirred overnight at room temperature. The solvent was removed to dryness and the remaining residue was diluted with 100 ml 1N HCl and 100 ml water. The aqueous layer was extracted several times with dichloromethane. The aqueous layer was made basic (pH˜9) with an alkaline resin (Bio Rad AG 1-X8). The resin was filtered and washed thoroughly with water. The combined washings were dried under reduced pressure to give a white solid (6.60 g).
