Reaction Steps

A solution of 3-(4-(3-fluoropropyl)phenyl)-4-nitropyridine (12 mg, 0.046 mmol) in 0.3 mL of triethyl phosphate was heated at 125° C. for 1 h. After cooling to rt, the volatiles were removed under reduced pressure and the residue was purified by silica chromatography (MeOH in DCM, 0% to 10%) to afford a off-white solid. This material was then further purified by reversed phase HPLC to yield 7-(3-fluoropropyl)-5H-pyrido[4,3-b]indole as a white solid (3 mg, 28%). 1H NMR (400 MHz, methanol-d4): δ 9.15 (s, 1H), 8.32 (d, J=4.4, 1H), 8.07 (d, J=8.0 Hz, 1H), 7.44 (d, J=6 Hz, 1H), 7.37 (m, 1H), 7.16 (dd, J=8.0, 1.2 Hz, 1H), 4.50 (t, J=6 Hz, 1H), 4.43 (t, J=6 Hz, 1H), 2.90 (t, J=7.6 Hz, 2H), 2.12-1.99 (m, 2H); MS (ESI) m/z [M+H]+229.
