PROCEDURE
实验过程
A glass microwave reaction vessel was charged with 4-(2-fluoro-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (400 mg, 0.643 mmol) and isoquinolin-7-amine (139 mg, 0.965 mmol)(Ark Pharm, Inc, Libertyville, Ill.) in dioxane (2 mL) and the reaction mixture was cooled at 0° C. To this solution, sodium bis(trimethylsilyl)amide (1.0 N in THF, 2 mL, 2 mmol) was mixed. The red solution was stirred at 0° C. for 1 h and 25° C. for 16 h. The reaction mixture was diluted with saturated NH4Cl and extracted with EtOAc (3×). The organic extract was washed with saturated NaCl and dried over MgSO4. The solution was filtered and concentrated under a vacuum. The crude material was adsorbed onto a plug of silica gel and purified by chromatography through a silica gel column (40 g), eluting with a gradient of 0% to 5% 2M NH3-MeOH in DCM, to provide N-(3-(4-(bis(4-methoxybenzyl)amino)-6-methyl-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-yl)isoquinolin-7-amine (150 mg, 31.3% yield) as a yellow solid. m/z (ESI, positive ion): 746 (M+H)+. 1H NMR (400 MHz, DMSO-d6): 6 ppm 2.63 (s, 3H) 2.82 (s, 3H) 3.06-3.10 (m, 4H) 3.57 (s, 2H) 3.70 (s, 3H) 3.75 (s, 3H) 4.86 (s, 4H) 6.84-6.97 (m, 4H) 7.30 (t, J=6.85 Hz, 4H) 7.72 (d, J=5.48 Hz, 1H) 7.74-7.79 (m, 1H) 7.82-7.88 (m, 1H) 8.35 (d, J=5.67 Hz, 1H) 8.39 (d, J=2.35 Hz, 1H) 8.58 (d, J=1.76 Hz, 1H) 8.75 (d, J=2.35 Hz, 1H) 9.13 (s, 1H) 12.19 (s, 1H).
