Procedure
A mixture of 6-benzyl-3-(4-((2,4-difluorophenyl)fluoromethyl)piperidin-1-yl)-N-isopropyl-5,6,7,8-tetrahydropyrido[3,4-b]pyrazin-2-amine TFA salt (108.3 mg, 0.174 mmol) and Pd(OH)2 on carbon, (20 wt %, 11 mg, 0.016 mmol) in THF (1.7 mL) 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 (67.5 mg, 72.9%) as a yellow film. 1H NMR (400 MHz, methanol-d4) δ ppm 1.24 (dd, J=6.6, 2.3 Hz, 6H), 1.41-1.48 (br m, 1H), 1.52-1.74 (m, 2H), 1.97-2.14 (m, 2H), 2.61-2.73 (m, 2H), 2.99 (t, J=6.3 Hz, 2H), 3.38-3.49 (m, 2H), 3.50-3.55 (m, 2H), 4.14 (s, 2H), 4.14-4.21 (m, 1H), 5.53 (dd, J=46.5, 7.3 Hz, 1H), 6.95-7.10 (m, 2H), 7.46-7.55 (m, 1H); ESI-MS m/z [M+H]+ 420.3.
