实验步骤: 4-(4-Nitro-benzyl)-thiomorpholine 1,1-dioxide (110 mg, 0.41 mmol) is dissolved in MeOH (7 mL). To this solution is added FeCl3.6H2O (−20 mg, 0.07 mmol) and active Charcoal (12 mg, 1.0 mmol). The suspension is heated to reflux. Hydrazine hydrate (0.5 mL) is added, and reflux is continued for 4 h until full conversion, the active Charcoal is filtered off through Celite, and the MeOH is removed under reduced pressure. The residue (85 mg, 86%) is directly used in the next step. The suspension is heated to reflux reflux the active Charcoal is filtered off through Celite the MeOH is removed under reduced pressure
