Reaction Steps

A mixture of benzyl 2-oxa-bicyclo[2.2.1]heptan-5-ylcarbamate (0.50 g, 2.0 mmol) and Pd/C (10%, 50 mg) in methanol (20 mL) was stirred under hydrogen atmosphere (1 atm) at room temperature for 16 hours. After completion of the reaction, the reaction mixture was adjusted to pH around 4 by 1M HCl in methanol. The mixture was filtered through Celite® and concentrated under reduced pressure to give 2-oxa-bicyclo[2.2.1]heptan-5-amine hydrochloride (300 mg, 100% yield) as a solid. 1H NMR (500 MHz, CD3OD) δ 4.43 (s, 1H), 3.72-3.70 (m, 1H), 3.54 (d, J=7.5 Hz, 1H), 3.50-3.48 (m, 1H), 2.76 (s, 1H), 2.20-2.15 (m, 1H), 1.96 (d, J=11.0 Hz, 1H), 1.78 (d, J=11.0 Hz, 1H), 1.61 (d, J=11.0 Hz, 1H).
