实验步骤: Indole-3-carboxylic acid (2.50 g, 0.0155 mol) was suspended in dichloromethane (60 ml) and treated with oxalyl chloride (1.62 ml, 0.0186 mol), followed by a drop of dry DMF. The reaction mixture was then stirred at room temperature overnight, before being evaporated under reduced pressure and dried in vacuo. The product was then redissolved in dichloromethane (50 ml) and added slowly to a solution of N,O-dimethylhydroxylamine hydrochloride (1.59 g, 0.0163 mol) in dichloromethane (50 ml) containing triethylamine (4.53 ml, 0.0326 mol) under argon. The resultant mixture was then stirred at room temperature for 2h, before being washed with water, followed by aq. NaHCO3. The organic layer was then dried (Na2SO4), evaporated under reduced pressure and dried in vacuo to yield the title compound as white solid (2.46 g, 78%). before being evaporated under reduced pressure dried in vacuo The product was then redissolved in dichloromethane (50 ml) before being washed with water The organic layer was then dried (Na2SO4) evaporated under reduced pressure dried in vacuo
