실험 절차

To a solution of 3-(4-nitro-1H-pyrazol-1-yl)propanal (200 mg, 1.18 mmol) in MeOH (12.0 mL), 5-methoxyindoline (176 mg, 1.18 mmol) was added. This reaction mixture was stirred at rt for 1 h, then NaBH4 (121 mg, 3.20 mmol) was added and stirred for another 30 min at rt. The reaction mixture was quenched with water and extracted with EtOAc (2×). The combined org. layers were dried (MgSO4), filtered and the solvent was removed under reduced pressure to yield 5-methoxy-1-(3-(4-nitro-1H-pyrazol-1-yl)propyl)indoline, which was used in the next step without further purification. LC-MS conditions B: tR=0.56 min, [M+H]+=303.15.
