실험 절차

Intermediate 3 (5,8-Dibromo-[1,2,4]triazolo[1,5-a]pyrazine, 140 mg, 0.50 mmol), Intermediate 6 (4-(1-morpholinomethyl) thiazol-2-ylamine, 120 mg, 0.60 mmol), sodium tert-butoxide (68 mg, 0.71 mmol), palladium dibenzylidene acetone (19 mg, 0.02 mmol) and Xantphos (23 mg, 0.04 mmol) were suspended in toluene (4 mL). The mixture is degassed with nitrogen for 5 min and then stirred at 90° C. for 16 h. The solvent is evaporated in vacuo to leave a brown residue. The residue is purified by column chromatography, eluting with 2% methanolic ammonia (7 N) in dichloromethane to give the title compound as a yellow powder (53 mg, 27%). 1H NMR (400 MHz, d6-DMSO) δ 2.53 (s, 4H, CH2CH2), 3.51 (s, 2H, CH2), 3.61 (m, 4H, CH2CH2), 6.99 (s, 1H), 8.13 (s, 1H), 8.61 (s, 1H), 8.75 (s, 1H).
