실험 절차

3-benzyl-N,N-dimethyl-3-azabicyclo[3.2.1]octan-8-amine (80 mg, 0.45 mmol) was dissolved in MeOH (10 ml) and the atmosphere was replaced with N2 (3×). 10% Pd/C (cat.) was added and the atmosphere was replaced with H2 (3×). The resulting reaction mixture was stirred at RT at balloon pressure overnight. When TLC showed no more UV active spot the Pd/C was filtered off (always keeping wet with MeOH) and the filtrate was concentrated which gave N,N-dimethyl-3-azabicyclo[3.2.1]octan-8-amine (44 mg) in 87% yield. 1H NMR (400 MHz, MeOD) δ ppm 3.45 (d, J=12.13 Hz, 2H) 2.88 (dd, J=12.38, 2.78 Hz, 2H) 2.35 (d, J=2.02 Hz, 2H) 2.31-2.23 (m, 6H) 2.11 (t, J=4.80 Hz, 1H) 2.06-1.92 (m, 2H) 1.89-1.79 (m, 2H)
