실험 절차

To a solution of 0.723 g (2.072 mmol) of the product of Example 187 in 70 mL of carbon tetrachloride was added 0.406 g (2.279 mmol) of N-bromosuccinimide and 0.14 g of dibenzoyl peroxide. The resulting mixture was heated to reflux for 18 h and then cooled to room temperature, washed with sodium bisulfite solution and water, dried over MgSO4, filtered and concentrated in vacuo. The residue was titurad with ether/hexanes (1:1) and then filtered to provide 0.504 g (57%) of the desired product as a white solid. Electrspray Mass Spec: 428 (M+H).
