反应详情

The compound (70.0 mg) obtained in Example 1-4 was added with a 40% methylamine/methanol solution (3.0 ml) and then stirred at room temperature for 14 hours. After completion of the reaction, the solvent was distilled off. Then, the residue was added with a 1 mol/l sodium hydroxide aqueous solution and chloroform to extract the aqueous layer therefrom with chloroform. The extract was dried with anhydrous sodium sulfate and the solvent was distilled off, thereby obtaining the subject compound (65.5 mg) as a colorless viscous liquid.
