실험 절차
A pear shaped flask was charged with 4-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-amine (0.20 g, 0.46 mmol, Example #7, Step B) and 2-chlorobenzo[d]oxazole (0.18 g, 1.1 mmol, TCI) in DMF (5.0 mL). To the suspension was added K2CO3 (0.16 g, 1.1 mmol) and the mixture was heated to about 65° C. for about 8.5 h. The mixture was cooled to room temperature and the solvent was removed under reduced pressure. The residue was dissolved into EtOAc (25 mL) and washed with water and brine (25 mL each). The organic solution was dried over anhydrous MgSO4, filtered, and concentrated to dryness under reduced pressure to give N-(4-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-yl)benzo[d]oxazol-2-amine (0.26 g, 95%, 95% purity by ELSD): LC/MS (Table 2, Method d) Rt=1.48 min; MS m/z: 554 (M+H)+.
