A solution of 3-(azidomethyl)-2-phenyl-N-[(1s)-1-phenylpropyl]quinoline-4-carboxamide (2d) (1000 mg, 2.37 mmol) in ethanol (200 mL) were added Pd/C (10%, 1190 mg) and HCl (2N, 2.5 mL) was added. The reaction mixture were hydrogenated under 50 psi H2 at RT for 1.5 h. The catalyst was removed by filtration through a thick layer of diatomaceous earth, the filter was washed with ethanol and the washes and the ethanol solvent was combined and concentrated in vacuo. Crystallization from dichloromethane and ether afforded the title compound (940 mg, 92%) as a hydrogen chloride salt. 1H NMR (300 MHz, CDCl3) δ 0.92 (t, 3H), 2.01 (m, 2H), 3.18 (b, 3H), 4.39 (t, 2H), 5.16 (q, 1H), 7.30 (d, 2H), 7.34 (d, 2H), 7.39 (m, 1H), 7.78 (m, 2H), 7.84 (m, 2H), 8.08 (m, 1H), 8.30 (m, 2H), 8.44 (m, 2H). MS APCI, m/z=396 (M+1). LCMS: 1.70 min.
