Reaction Steps

To stirred solution of ethyl-1-(3-(benzylamino)-4-nitrophenyl)piperidine-3-carboxylate (1 g, 3.1 mmol) in 10 ml THF: H2O (3:1) was added lithium hydroxide (0.35 g, 15.4 mmol) at room temperature. The resulting mixture was stirred for 5 h, solvent was evaporated and residue was dissolved in water washed with dichloromethane. The aqueous layer was then neutralised with 2M HCl to get yellow solid 1-(3-(benzylamino)-4-nitrophenyl)piperidine-3-carboxylic acid (0.7 g), 86% yield: 1H NMR (500 MHz, DMSO): δ 1.55 (m, 1H), 1.87 (m, 2H), 2.10 (m, 1H), 2.62 (m, 1H), 3.07 (m, 1H), 3.30 (m, 1H), 3.60 (m, 1H), 3.82 (dd, J=3.6, 5.6 Hz, 1H), 4.55 (d, J=5.4 Hz, 2H), 5.92 (d, J=2.5 Hz, 1H), 6.28 (dd, J=2.6 Hz, 1H), 7.32 (m, 2H), 7.41 (m, 3H), 8.12 (d, J=9.6 Hz, 1H), 8.8 (m, 1H).
