PROCEDURE

实验过程

A solution of 2-(2,6-dichloro-3-nitro-phenyl)-N-(2-formyl-phenyl)-acetamide (0.7 g, 1.99 mmol) and Na2CO3 (1.0 g) in MeOH (150 mL) is heated for 30 minutes at 70° C. After filtration of the reaction mixture, the solvent is removed by concentration to give crude product. The crude product is purified by flash silica gel column, eluting with CH2Cl2 (100%) gradient to CH2Cl2/MeOH (2N NH3) (97/3%), resulting in the titled intermediate as a solid (0.288 g, 41.3%).
