실험 절차

To a solution of 1-((1S,3R)-3-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)cyclopentyl)-1H-pyrrole-3-carbaldehyde (0.050 g, 0.105 mmol) in THF (2 mL) was added iodine (0.083 g, 0.327 mmol) and aqueous NH4OH (28-30% w/v, 0.733 mL, 5.27 mmol). The reaction mixture was stirred at ambient temperature for about 24 h. The reaction mixture was diluted with saturated aqueous Na2SO3 (30 mL) and EtOAc (30 mL). The layers were partitioned and the organic layer was dried over anhydrous MgSO4, filtered, and the solvent was removed under reduced pressure to give 1-((1S,3R)-3-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)cyclopentyl)-1H-pyrrole-3-carbonitrile (0.05 g, 100%): LC/MS (Table 1, Method a) Rt=2.33 min; MS m/z: 472 (M+H)+.
