실험 절차

To a degassed solution of 5-(5-fluoro-pyridin-3-ylethynyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (60 mg, 0.188 mmol) in MeOH (3 mL) were added 10% dry Pd—C (35 mg) and ammonium formate (59 mg, 0.940 mmol). The reaction mixture was stirred at 75° C. for 1 h. The reaction mass was filtered through Celite and the filtrate concentrated under reduced pressure to afford crude product, which was purified by reverse phase HPLC to yield 5-[2-(5-fluoro-pyridin-3-yl)-ethyl]-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR (CD3OD, TFA salt) δ (ppm): 8.3 (s, 1H), 7.9 (s, 1H), 7.38 (d, 1H), 7.21 (s, 1H), 7.2 (d, 1H), 7.0 (d, 1H), 4.62 (d, 1H), 4.4 (t, 2H), 4.3 (d, 1H), 3.78 (m, 1H), 3.4 (m, 1H), 3.18 (t, 2H), 3.1 (s, 3H), 2.9 (m, 1H), 2.8 (m, 1H), 2.4 (s, 3H).
