Participants

Reaction Steps

By a method similar to Example 763, using 2-(4,5,6,7-tetrafluoro-1H-indol-3-yl)ethylamine (484 mg, 2.08 mmol), ethanol (45 mL), 3-(2,2,2-trifluoroethoxy)benzaldehyde (425 mg, 2.08 mmol), anhydrous sodium sulfate (3.5 g) sodium borohydride (236 mg, 6.24 mmol) to give the free base of the title compound as a straw colored solid. Recrystallize from methylene chloride to obtain the title compound: mp 107.2-108.2° C. 1H NMR (400 MHz, dmso-d6): 11.92 (br s, 1H), 7.32 (s, 2H), 6.95-6.99 (m, 2H), 6.87 (dd, 1H, J=2.4, 8.0 Hz) 4.68 (q, 2H, J=8.8 Hz), 3.70 (s, 2H), 2.88 (t, 2H, J=7.2 Hz) 2.75 (t, 2H, J=7.2 Hz). MS (ES+): m/e 421.1 (M+1). CHN (for C19H15F7N2O.1HCl.0.20H2O) calcd: C, 53.83; H, 3.66; N, 6.61. found: C, 53.75; H, 3.33; N, 6.
