실험 절차

The product from Example 11.2 (530 mg, 1.82 mmol) and hydroxylamine hydrochloride (0.549 g, 7.9 mmol) were mixed with ethanol (50 mL). To this stirred solution was added sodium bicarbonate (663 mg, 7.9 mmol) and the mixture was heated at 70° C. for 3 h. The solvent was removed in vacuo and the residue dissolved in a mixed solvent (dichloromethane/ethanol 200 mL: 10 mL), washed with water, dried (Na2SO4) and concentrated in vacuo to give the desired compound (472 mg, 80%).
