2-Aminobenzaldehyde → 2-(2,6-dichloro-3-nitro-phenyl)-N-(2-formyl-phenyl)-acetamide

참여 물질

반응 단계

A solution of (2,6-dichloro-3-nitro-phenyl)-acetic acid (0.90 g, 3.35 mmol) in thionyl chloride (15 mL) is refluxed for one hour. The solvent is removed by concentration and dry toluene is added to thoroughly remove thionyl chloride. To the solution of acid chloride in dry dichloromethane (30 mL) is added (drop-wise) a solution of 2-aminobenzaldehyde (0.365 g, 3.02 mmol) in dichloromethane (5.0 mL). The mixture is stirred at room temperature for 2 hours. The reaction mixture is diluted with EtOAc and washed with saturated K2CO3 and brine. The organic layer is dried, filtered and concentrated to give crude product (0.94 g, 88.6%).
