A mixture solvent of methanol and water (9:1) was added to the reaction solution, an aqueous solution of saturated ammonium chloride was further added thereto, followed by stirring at room temperature for 10 minutes, then, extracted with ethyl acetate, dried over anhydrous magnesium sulfate, then, the solvent was evaporated to obtain the title compound (285 mg, 89%) as a yellow oil.
