実験手順

This compound may be prepared using methods as described for Compound 6, step 4 using 5-(5-bromo-[1,2,4]triazolo[1,5-a]pyrazin-8-ylamino)-2-morpholin-4-yl-benzamide (140 mg, 0.33 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (130 mg, 0.67 mmol) and Pd(PPh3)4 (96 mg, 0.083 mmol) in 1.5M K2CO3 (aq) (1.93 mL) and dioxane (3.44 mL). The crude material is purified by silica gel column chromatography eluting with DCM followed by 99:1 then 97:3 then 95:5 DCM:NH3 (7M in MeOH) to afford the title compound as a white solid (40.5 mg, 30%). 1H-NMR (400 MHz, d6-DMSO) δ(ppm) 2.96 (4H, m), 3.79 (4H, m), 7.28 (2H, d), 7.45 (1H, m), 7.54 (1H, br s), 8.01-8.09 (1H, dd), 8.25 (1H, s), 8.50 (1H, d), 8.69 (1H, br s), 8.78 (1H, s), 9.98 (1H, s), 13.3 (1H, br s). LCMS: Rt 2.23 min (96.9%), m/z (APCI) 406 (M+H)+.
