実験手順
The solution of 12-2 (0.3 g, 0.92 mmol) in 25 mL of acetic acid was heated to 80° C. for 8 h. The volatile was removed in vacuo and the residue was neutralized with Na2CO3 solution to pH:7. The mixture was extracted with ethyl acetate (100 mL) and washed with brine. The organic layer was dried over anhydrous Na2SO4. After filtration and concentration, a residue was obtained, which was purified by preparative TLC to give 12-3 (68 mg, 23.9%)
