Reaction Steps

To a solution of (1S)-2-(5-chloro-2-methylphenyl)-1-methylethyl azide (500 mg, 2.38 mmol) in 50 mL of EtOAc was added Pd/C (150 mg of 10% Pd) and the mixture was hydrogenated under hydrogen balloon for 20 min. The catalyst was removed by filtration through celite, then passed through silicagel plug eluting first with EtOAc (40 mL), then MeOH/EtOAc/NH4OH 20:75:5 (120 mL). The fraction with product was evaporated to give (1S)-2-(5-chloro-2-methylphenyl)-1-methylethylamine (210 mg, 48%) as pale oil. ESI-MS: m/z (MH+) 184.4. 1H NMR (300 MHz, CDCl3): δ 7.12 (s, 1H), 7.08 (s, 2H), 3.16 (m, 1H), 2.48-2.70 (m, 2H), 2.28 (s, 3H), 1.23 (s, 2H), 1.13 (d, J=6.21 Hz, 3H).
