PROCEDURE
实验过程
A mixture of 4-((2,4-difluorophenyl)fluoromethyl)piperidine hydrochloride (74.0 mg, 0.279 mmol), 6-benzyl-3-chloro-N-isopropyl-5,6,7,8-tetrahydropyrido[3,4-b]pyrazin-2-amine TFA salt (100 mg, 0.232 mmol), sodium tert-butoxide (66.9 mg, 0.696 mmol), BINAP (21.7 mg, 0.035 mmol) and Pd2(dba)3 (10.6 mg, 0.012 mmol) in toluene (1.2 mL) was heated at 100° C. in a sealed tube for 14 h. The mixture was purified by HPLC Method A to give the title compound as a TFA salt (108.3 mg, 74.8%) as a yellow solid. 1H NMR (400 MHz, methanol-d4) δ ppm 1.23 (dd, J=6.4, 2.4 Hz, 6H), 1.39-1.47 (m, 1H), 1.51-1.72 (m, 2H), 1.95-2.12 (m, 2H), 2.58-2.70 (m, 2H), 3.04 (br s, 2H), 3.36-3.83 (m, 4H), 4.09-4.21 (m, 3H), 4.51 (br s, 2H), 5.52 (dd, J=46.2, 7.3 Hz, 1H), 6.97-7.07 (m, 2H), 7.45-7.59 (m, 6H); ESI-MS m/z [M+H]+ 510.4.
