Reaction Steps
A mixture of Example 1E (0.048 g, 0.133 mmol) and tert-butyl 2-(4-aminophenyl)piperidine-1-carboxylate (0.059 g, 0.213 mmol) was heated in a capped vial at 120° C. for 1 hour. The reaction mixture was treated with ethyl acetate and washed with saturated NaHCO3. The organic layer was dried over MgSO4, filtered, and concentrated. The residue was dissolved in CH2Cl2 (2 mL) and treated with trifluoroacetic acid (0.103 ml, 1.334 mmol). The mixture was stirred at 35° C. for 5 hours, concentrated, and purified by HPLC (see protocol in Example 1F) to provide the title compound as a trifluoroacetic acid salt. 1H NMR (500 MHz, CD3OD) δ 1.89-1.72 (m, 2H), 2.16-1.96 (m, 4H), 3.25-3.16 (m, 1H), 3.51-3.43 (m, 1H), 4.29-4.22 (m, 1H), 7.08 (d, J=1.9 Hz, 1H), 7.62-7.50 (m, 5H), 7.72-7.66 (m, 1H), 7.97-7.86 (m, 3H), 9.19 (s, 1H). MS (ESI+) m/z 472.2 (M+H)+.
