1-Methyl-2-imidazolecarboxaldehyde → HCID 11719896, compound

Participants

Reaction Steps

The compound (12.5 mg) obtained in Example 38-1 was dissolved in methanol (2.0 ml) and added with 1-methyl-2-imidazole carboxaldehyde (4.4 mg) and sodium cyanoborohydride (4.2 mg). The solution was adjusted to pH 4 with acetic acid and stirred at room temperature for 8 hours. The residue obtained by concentration of the solution was added with a saturated aqueous sodium hydrogen carbonate solution to neutralize the solution and the whole was subjected to extraction with chloroform. The organic layer was washed with a saturated aqueous sodium hydrogen carbonate solution and dried with anhydrous sodium sulfate. The residue obtained by distilling the solvent off was purified through silica gel column chromatography (chloroform/methanol), thereby obtaining the subject compound (7.7 mg) as a colorless oily substance.
