实验步骤: Phosphorous oxychloride (1.9 mL, 20 mmol) was added to a suspension of 4-bromo-1H-indole-2-carboxylic acid amide (1.32 g, 5.5 mmol.) in toluene (10 mL) and the mixture was stirred at reflux for 45 min. On cooling, the mixture was poured into an aqueous Na2CO3 solution (sat., 50 mL) and the mixture stirred until effervescence had subsided. The layers were separated, the aqueous phase extracted with EtOAc and the combined organic layers dried (MgSO4) and evaporated to dryness. The crude material was purified by column chromatography to afford the title compound as a solid (1.00 g, 82%). at reflux for 45 min On cooling the mixture stirred until effervescence The layers were separated the aqueous phase extracted with EtOAc the combined organic layers dried (MgSO4) evaporated to dryness The crude material was purified by column chromatography

实验步骤: Oxalyl chloride (0.9 mL, 10 mmol) was added to a suspension of 4-bromo-1H-indole-2-carboxylic acid (2.1 g, 8.8 mmol) in DCM and the mixture was stirred for 2 h. The solution formed was added drop-wise to a stirring mixture of ammonia (37%, 50 mL) and ice (50 mL). The resulting mixture was allowed to stand for 3 days. The mixture was filtered and the filtrate extracted with EtOAc. The solid from the filtration was dissolved in EtOAc and the organic solutions were combined, dried (MgSO4) and then evaporated to afford the title compound as a brown solid (2.1 g, 100%). The solution formed was added drop-wise to stand for 3 days The mixture was filtered the filtrate extracted with EtOAc The solid from the filtration was dissolved in EtOAc dried (MgSO4) evaporated
