Sodium hydride → HCID 23079305, compound

Participants

Reaction Steps

In DMF (15 ml), 2-imidazole carboxaldehyde (300 mg) was dissolved. Then, the compound (1.01 g) obtained in Example 92-1 and sodium hydride (137 mg) were added to the solution, and the whole was stirred at room temperature for 5 days. After completion of the reaction, the solvent was distilled off and the residue was then added with chloroform, followed by washing with water and saturated saline solution. The resultant was dried with anhydrous sodium sulfate, and the solvent was distilled off. Subsequently, the residue was purified through silica gel column chromatography (chloroform/methanol), thereby obtaining the subject compound (457 mg) as a yellow viscous liquid.
