PROCEDURE

实验过程

A mixture of (R)-4-(2-fluoro-5-(1-(4-(methylsulfonyl)piperazin-1-yl)ethyl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (Example 146, Step 6) (140 mg, 0.220 mmol), 5-fluoroquinolin-7-amine (35.7 mg, 0.220 mmol) and lithium bis(trimethylsilyl)amide (1.0 M in THF; 0.661 mL, 0.661 mmol, Aldrich) in THF (3 mL) was stirred at 0° C. for 1 h. The reaction mixture was diluted with saturated NH4Cl (10 mL) and extracted with EtOAc (2×30 mL). The organic extract was washed with saturated NaCl (10 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as yellow oil. The crude product was purified by silica gel chromatography eluting with EtOAc to give (R)—N-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-(1-(4-(methylsulfonyl)piperazin-1-yl)ethyl)pyridin-2-yl)-5-fluoroquinolin-7-amine (122 mg, 0.157 mmol, 71.2% yield). 1H NMR (300 MHz, CDCl3) δ 1.40 (d, J=6.72 Hz, 3H) 2.57 (dd, J=11.91, 4.17 Hz, 4H) 2.65 (s, 3H) 2.67 (s, 3H) 3.07-3.24 (m, 4H) 3.81 (s, 3H) 4.76-4.98 (m, 4H) 6.86 (dd, J=12.28, 8.62 Hz, 4H) 7.11-7.25 (m, 9H) 7.38-7.52 (m, 1H) 7.82 (d, J=8.48 Hz, 1H) 8.42 (d, J=2.19 Hz, 1H) 8.77 (d, J=2.34 Hz, 1H) 8.91 (d, J=2.49 Hz, 1H) 9.14 (d, J=2.05 Hz, 1H) 12.57 (s, 1H). m/z (ESI, +ve ion) 778.1 (M+H)+.
