This compound may be prepared using methods as described for Compound 6, step 4 using (5-bromo-[1,2,4]triazolo[1,5-a]pyrazin-8-yl)-(4-morpholin-4-yl-phenyl)-amine (0.2 g, 0.53 mmol), 5-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (222 mg, 1.06 mmol), and Pd(PPh3)4 (0.154 mg, 0.134 mmol) in 1.5M Na2CO3 (aq) (2.84 mL, 4.26 mmol) and dioxane (8.5 mL). The reaction mixture is purified by silica gel column chromatography using 98:2 and 97:3 DCM:NH3 (7M in MeOH) to give the title compound (15 mg, 7.5%). Conversion into the mesylate salt using 0.1M methanesulfonic acid in MeOH (0.398 mL) affords the title compound (15 mg) as a pale green solid. 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 2.41 (3H, s, MsOH), 2.46 (3H, s), 3.20 (4H, m), 3.71 (4H, m), 7.11 (2H, d), 7.74 (1H, s), 7.97 (2H, d), 8.15 (1H, s), 8.69 (1H, s), 9.88 (1H, s). LCMS: Rt 2.41 min (98.3%), m/z (APCI) 377 (M+H)+.
