Procedure

A mixture of 6-benzyl-2-(4-(2-fluoro-4-methoxyphenoxy)piperidin-1-yl)-N-isopropyl-5,6,7,8-tetrahydropyrido[3,4-b]pyrazin-3-amine TFA salt (51 mg, 0.082 mmol) and Pd(OH)2 on carbon (20 wt %, 5 mg, 7.12 μmol) in THF (820 μL) was stirred under an atmosphere of hydrogen gas (balloon) at rt. After 2 h, the mixture was purified by HPLC Method A to give the title compound as a TFA salt (41.2 mg, 95%) as a yellow foam. 1H NMR (400 MHz, methanol-d4) δ ppm 1.24 (d, J=6.6 Hz, 6H), 1.88-1.98 (m, 2H), 2.05-2.14 (m, 2H), 2.94-3.03 (m, 4H), 3.35-3.43 (m, 2H), 3.54 (t, J=6.3 Hz, 2H), 3.76 (s, 3H), 4.10-4.21 (m, 3H), 4.32-4.39 (m, 1H), 6.67 (ddd, J=8.9, 3.0, 1.5 Hz, 1H), 6.74 (dd, J=12.8, 2.9 Hz, 1H), 7.07 (t, J=9.2 Hz, 1H); ESI-MS m/z [M+H]+ 416.3.
