실험 절차

To a solution of tert-butyl 6-nitro-1,3,4,5-tetrahydro-2H-pyrido[4,3-b]indole-2-carboxylate (15.6 g, 49.15 mmol) in ethanol (250 mL) was added a spatula tip of 10% Pd/C. The reaction mixture was shaken under a hydrogen atmosphere (15 psi, Parr apparatus) for 2 h. Upon removal from the Parr apparatus, the reaction mixture was filtered through Celite. The Celite was washed with ethanol and the combined filtrates were concentrated in vacuo to give tert-butyl 6-amino-1,3,4,5-tetrahydro-2H-pyrido[4,3-b]indole-2-carboxylate, quantitatively as a white solid: 1H NMR (CDCl3, 500 MHz) δ 1.42-1.67 (m, 9H), 2.74-2.85 (m, 2H), 3.58 (brs, 2H), 3.79 (brs, 2H), 4.60 (brs, 2H), 6.53-6.56 (m, 1H), 6.89-6.99 (m, 2H), 7.77 (brs, 1H) ppm.
