실험 절차

A mixture of tert-butyl 3-pyridinylmethylcarbamate (4.3 g) and 5% rhodium on carbon (400 mg) in ethanol (50 mL) at 25° C. in a paar apparatus was stirred under hydrogen at 60 pounds per square inch for 27 hours, filtered through diatomaceous earth (Celite®), and concentrated. 1H NMR (300 MHz, CDCl3) δ 4.55 (b, 1H), 2.99 (m, 4H), 2.56 (t, 1H), 2.33 (t, 1H), 1.74 (m, 1H), 1.66 (m, 2H), 1.44 (s, 9H).
