Acetic Acid → HCID 10028389, compound

Participants

Reaction Steps

The compound (20.4 mg) obtained in Example 35-5 was dissolved in anhydrous methanol (2.0 ml) and added with sodium cyanoborohydride (9.50 mg), acetic acid (2.0 ml), and 2-imidazole carboxaldehyde (9.60 mg), followed by stirring at room temperature under a nitrogen atmosphere for 6.5 hours and a half. After completion of the reaction, the solvent was distilled off. The residue was dissolved in chloroform and added with a saturated aqueous sodium bicarbonate solution, followed by stirring. The solution was subjected to extraction with chloroform and the extract was then washed with a saturated aqueous sodium bicarbonate solution and saturated saline solution. Subsequently, the organic layer was dried with anhydrous sodium sulfate. The solvent was distilled off, and the residue was treated with hydrochloric acid and then purified through silica gel column chromatography (chloroform/methanol/water), thereby obtaining hydrochloride (4.50 mg) of the subject compound as a white solid.
