Diethyl azodicarboxylate (4.44 mL, 0.0282 mol) in 1 ml of THF was added to a mixture of 1-benzyl-3-[2-(hydroxymethyl)phenyl]pyrrolidin-3-ol (3.50 g, 0.0124 mol) and triphenylphosphine (7.40 g, 0.0282 mol) in tetrahydrofuran (50 mL, 0.6 mol) at room temperature. The mixture was stirred at room temperature overnight. The reaction solution was concentrated and the residue was flash chromatographed on silica gel column with 50% AcOEt in hexanes to give the desired compound (1.5 g, 46% yield). MS (ESI): 266.1 (M+H+).
