반응 단계

To a solution of 44 (620 mg, 2 mmol) in EtOH (15 mL) was added zinc powder (320 mg, 5.0 mmol) and NH4Cl (0.53 g, 10 mmol). The reaction mixture was heated at reflux overnight, filtered and the filtrate was concentrated to dryness. The residue was diluted with DCM (100 mL) and water (20 mL). The organic layer was separated, dried (MgSO4), filtered and concentrated to afford 600 mg (100%) of (1-tosyl-1H-indol-4-yl)methanamine (46) as yellow syrup: MS (ESI) m/z=284.1 [M−15]+.
