Reaction Steps

To a solution of Example 305A (100 mg, 0.196 mmol) and diisopropylethylamine (0.034 mL, 0.19 mmol) in acetonitrile (1 mL) was added cyclopropanamine (11 mg, 0.19 mmol) and the reaction mixture was heated at about 60° C. for about 1 hour. The reaction mixture was cooled to ambient temperature and hydrochloric acid (4 N in dioxane, 1 mL) was added. The reaction mixture was stirred at ambient temperature for about 16 hours. The reaction mixture was concentrated under reduced pressure and the crude material was purified by reverse-phase HPLC using acetonitrile/water (0.05 M ammonium acetate) gradient elution method to afford the title compound as the acetate salt. 1H NMR (400 MHz, DMSO-d6) δ ppm 10.18 (s, 1H), 8.28 (s, 1H), 8.56 (s, 1H), 7.81 (d, J=8.6 Hz, 1H), 7.49 (d, J=8.7 Hz, 1H), 7.30-7.45 (m, 5H), 5.64 (s, 2H), 3.45 (s, 2H), 2.18-2.26 (m, 1H), 1.89 (s, 3H), 0.37-0.45 (m, 2H), 0.29-0.37 (m, 2H). MS (ESI+) m/z 388 (M+H)+.
