実験手順

To a solution of the product of Example 2 in 5.0 mL of acetic acid-chloroform (1:1) at room temperature was added 0.299 g (1.682 mmol) of N-bromosuccinimide. The reaction was stirred for 18 h and then diluted with ether, washed with water and saturated sodium bicarbonate solution, dried over MgSO4, filtered and concentrated in vacuo. The tan solid residue was washed with ether-hexanes (1:1) to provide 0.504 g (81%) of the desired product as a tan solid. Electrospray Mass Spec: 406.1 (M+H)+
