실험 절차

According to the procedure described for Compound 6, step 1, 5,8-dibromo-[1,2,4]triazolo[1,5-a]pyrazine (0.5 g, 1.799 mmol), 4-(2-morpholin-4-yl-ethoxy)-phenylamine (0.6 g, 4.5 mmol) and N,N-diisopropylethylamine (0.47 mL, 2.7 mmol) in 2-propanol (6 mL) are stirred at 95° C. overnight. After evaporation of the solvent the residue is dissolved in DCM and washed with water (2×) and brine. The organic layer is dried over MgSO4, filtered and concentrated in vacuo to afford an oil purified by silica gel column chromatography. Elution with a 97:3 mixture DCM:MeOH gives the title compound (650 mg 86%) as a light yellow solid. LCMS: Rt 2.06 nm in (97.7%).
