Participants

Reaction Steps

An anhydrous methanol solution (0.50 ml) containing the compound (30.1 mg) obtained in Example 36-5 and 2-imidazole carboxaldehyde (10.1 mg) was added with trimethyl orthoformate (0.029 ml), and the whole was stirred at room temperature for 14 hours. Sodium borohydride (17.0 mg) was added thereto and the whole was stirred for 30 minutes. The solvent was distilled off. The residue was dissolved in chloroform, washed with a saturated aqueous sodium hydrogen carbonate solution, and dried with anhydrous sodium sulfate, and the solvent was distilled off, thereby obtaining the subject compound (30.4 mg).
