Participants

Reaction Steps

To a solution of 4-benzyl-1-(2-(3-(ethoxycarbonylmethyl)phenoxy)ethyl)piperidine (0.382 g, 1.00 mmol) in 5 mL of MeOH was added 5 mL of hydrazine hydrate. The resulting solution was allowed to stir at rt for 12 hr. The MeOH was evaporated in vacuo and water (10 mL) was added. A colorless solid precipitated. The solid was collected by filtration and dried in vacuo giving the title product (240 mg, 65%): mp 89-91° C.; 1H NMR (CDCl3) 1.31 (m, 2 H), 1.60 (m, 1 H), 1.62 (m, 2 H), 2.04 (t, J=11.7 Hz, 2 H), 2.52 (d, J=6.9 Hz, 2 H), 2.76 (t, J=6.0 Hz, 2 H), 2.95 (d, J=11.4 Hz, 2 H), 3.53 (s, 2 H), 3.83 (bs, 2 H), 4.08 (t, J=6.3 Hz, 2 H), 6.66 (s, 1 H), 6.79 (m, 3 H), 7.12-7.27 (m, 6 H).
