PROCEDURE

实验过程

A solution of 2-(2,6-dichloro-3-nitro-phenyl)-N-(3-formyl-pyridin-4-yl)-acetamide (5.0 g, 14.12 mmol) and Na2CO3 (2.5 g) in MeOH (300 mL) is heated for 15 minutes at 70° C. After filtration of the reaction mixture, the solvent is removed by concentration to give crude product, which is purified by flash silica gel column elute with CH2Cl2 (100%) gradient to CH2Cl2/MeOH (2N NH3) (93/7%) to give the titled intermediate as a solid (3.75 g, 77.7%).
