実験手順

This compound may be prepared using methods as described for Compound 6, step 4 using 5-bromo-N-(6-(4-isopropylpiperazin-1-yl)pyridin-3-yl)-[1,2,4]triazolo[1,5-a]pyrazin-8-amine (0.6 g, 1.44 mmol), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-2,3-dihydro-isoindol-1-one (0.56 g, 2.16 mmol) and Pd(PPh3)4 (0.416 g, 0.36 mmol) in 1.5M Na2CO3 (7.7 mL) and dioxane (23 mL). Purification by silica gel column chromatography eluting with DCM followed by 98:2 DCM:NH3 (7M in MeOH) affords the title compound (0.36 g, 53%) which is converted into the mesylate salt using 1M methanesulfonic acid in MeOH (0.77 mL). After trituration with diethyl ether and DCM the title compound is isolated as a solid (0.410 g). 1H-NMR (400 MHz, d6-DMSO) δ(ppm) 1.35 (6H, d), 2.35 (3H, s, MsOH), 3.04 (2H, t), 3.20-3.27 (2H, m), 3.56-3.63 (3H, m), 3.89 (2H, d), 4.52 (2H, s), 7.09 (2H, d), 7.85 (1H, d), 7.95-8.01 (3H, m), 8.10 (1H, d), 8.24 (1H, s), 8.72 (1H, s), 8.74 (1H, s), 9.27 (1H, br s), 10.07 (1H, s). LCMS: Rt 2.93 min (97.9%), m/z (ES+) 469 (M+H)+.
