Reaction Steps

To a solution of (1S)-2-(3,4-difluoro-2-methylphenyl)-1-methylethyl azide (503 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 1 h. The catalyst was removed by filtration through celite, then passed through silica gel 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-(3,4-difluoro-2-methylphenyl)-1-methylethylamine (376 mg, 85%) as pale oil. ESI-MS: m/z (MH+) 186.4. 1H NMR (300 MHz, CDCl3): δ 6.82-6.97 (m, 2H), 3.12 (m, 1H), 2.48-2.73 (m, 2H), 2.25 (s, 3H), 1.34 (s, 2H), 1.12 (d, J=6.39 Hz, 3H).
