Procedure

To a solution of 0.139 g (0.412 mmol) of the product of Example 31 in 2.0 mL of DMF was added 0.70 g (1.03 mmol) of imidazole and 0.075 g (0.495 mmol) of t-butyldimethylsilyl chloride. The reaction mixture was then srtied at room temperature for 3h and then diluted with 75 mL of ether. The resulting mixture was washed with water and brine, dried over MgSO4, filtered and concentrated in vacuo to provide 0.179 g (96%) of the desired product as a white solid. Electrospray Mass Spec: 452.2 (M+H)+
