Participants

Reaction Steps

To a solution of 4-[(S)-2-(4-benzyl-phenoxymethyl)-pyrrolidin-1-yl]-butyric acid methyl ester (0.37 g, 1 mmol) in toluene (2 mL) was added 1.5M diisobutylaluminum hydride in toluene (2 mL, 3 mmol) at −60° C. and then stirred the reaction at −30 to −20° C. for 2 h, followed by addition of 15% AcOH dropwise. The reaction was stirred at room temperature for 30 minutes and formed white solid was filtered and washed with acetone. The filtrate was concentrated in vacuo to yield the title compound as a white solid (0.22 g, 79%); MS; m/z 340.8 (M+H). 1H NMR (400 HMz, CDCl3) δ 1.61-2.26 (m, 8H), 2.79 (m, 1H), 2.85 (m, 1H), 3.25 (m, 2H), 3.42 (m, 2H), 3.54 (m, 1H). 3.68 (m, 1H), 3.75 (m, 1H), 3.92 (s, 2H), 6.82 (d, J=8.8 Hz, 2H), 7.09-7.21 (m, 5H), 7.28 (m, 2H).
