Procedure

A mixture of 6-benzyl-2-(4-((2,4-difluorophenyl)fluoromethyl)piperidin-1-yl)-N-isopropyl-5,6,7,8-tetrahydropyrido[3,4-b]pyrazin-3-amine TFA salt (60 mg, 0.096 mmol) and Pd(OH)2 on carbon, (20 wt %, 6 mg, 8.54 μmol) in THF (960 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 (47.6 mg, 93%) as a yellow foam. 1H NMR (400 MHz, methanol-d4) δ ppm 1.23 (dd, J=6.4, 2.4 Hz, 6H), 1.41-1.49 (m, 1H), 1.52-1.74 (m, 2H), 1.98-2.14 (m, 2H), 2.68 (qd, J=12.6, 2.5 Hz, 2H), 2.96 (t, J=6.3 Hz, 2H), 3.40-3.51 (m, 2H), 3.52 (t, J=6.3 Hz, 2H), 4.10-4.16 (m, 1H), 4.16 (s, 2H), 5.53 (dd, J=46.5, 7.6 Hz, 1H), 6.97-7.08 (m, 2H), 7.47-7.55 (m, 1H); ESI-MS m/z [M+H]+ 420.3.
