Procedure

A solution of 2-(4-(2,4-difluorophenoxyl)piperidin-1-yl)-N-isopropyl-5,6,7,8-tetrahydropyrido[3,4-b]pyrazin-3-amine TFA salt (45 mg, 0.087 mmol) in DCM (870 μL) at 0° C. was treated with triethylamine (36.4 μL, 0.261 mmol), followed by pyrrolidine-1-carbonyl chloride (19.2 μL, 0.174 mmol). The reaction mixture was allowed to stir for 30 min, gradually warming to room temperature. The reaction mixture was concentrated under reduced pressure and purified directly by HPLC Method B, with the exception that a Phenomenex Gemini® C18, 5 μm, ID 30×75 mm column was used, using a 50% to 80% ACN gradient to give the title compound, as a TFA salt, as a pale yellow solid (10.6 mg, 19.8%). 1H NMR (400 MHz, methanol-d4) δ ppm 1.33 (d, J=6.3 Hz, 6H), 1.89 (m, 4H), 1.97 (m, 2H), 2.14 (m, 2H), 2.81 (t, J=5.8 Hz, 2H), 3.13 (m, 2H), 3.46 (m, 6H), 3.61 (t, J=5.8 Hz, 2H), 4.12 (septet, J=6.4 Hz, 1H), 4.38 (s, 2H), 4.51 (tt, J=7.2, 3.6 Hz, 1H), 6.88 (m, 1H), 6.99 (ddd, J=11.4, 8.5, 3.0 Hz, 1H), 7.18 (td, J=9.2, 5.6 Hz, 1H); ESI-MS m/z [M+H]+ 501.6.
