Reaction Conditions

Reaction Steps

The compound (64.0 mg) obtained in Example 4-1 was dissolved in methanol (1.3 ml) and added with acetic acid (0.065 ml) and 1-methyl-2-imidazole carboxaldehyde (16.6 mg) and the whole was cooled to 0° C. Then, the solution was added with sodium cyanoborohydride (14.2 mg) and stirred at room temperature for 2 days. After completion of the reaction, the solvent was distilled off under reduced pressure and the residue was then dissolved in chloroform. After washing with a 1 mol/l sodium hydroxide aqueous solution, the solution was subjected to extraction with chloroform. The organic layer was washed with a saturated saline solution and dried with anhydrous sodium sulfate.
