Acetic Acid → HCID 67103666, compound

Participants

Reaction Steps

The compound (403 mg) obtained in Example 62-2 was dissolved in anhydrous methanol (16 ml) and added with 1-methyl-2-imidazole carboxaldehyde (151 mg) and sodium cyanoborohydride (172 mg). After the solution was adjusted to pH 5 with acetic acid, the whole was stirred at room temperature for 18 hours. After completion of the reaction, the solvent was distilled off. The resultant was added with a 1 mol/l sodium hydroxide aqueous solution and the whole was subjected to extraction with chloroform. The resultant was dried with magnesium sulfate and the solvent was distilled off. The resultant was purified through silica gel column chromatography (chloroform/ethyl acetate), thereby obtaining the subject compound (333 mg) as a colorless oily substance.
