Participants

Reaction Steps

Diisopropylazodicarboxylate (40% in toluene, 5.7 g, 11.3 mmol) was added to a solution of (2S)-2-(4-hydroxyphenyl)-4-benzylmorpholine (2.0 g, 7.43 mmol), triphenylphosphine (3.0 g, 11.4 mmol) and 1-acetyl-4-hydroxypiperidin (1.6 g, 11.2 mmol) in tetrahydrofuran (40 ml) at room temperature and the mixture stirred for 10 hours. The mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over magnesium sulfate, and concentrated in vacuo. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography eluting 10-50% ethyl acetate in hexane to furnish (2S)-2-(4-(1-acetylpiperidin-4-yloxy)phenyl)-4-benzylmorpholine (1.68 g, 57%) as colorless oil.
