Procedure

To a solution of 1.00 g (2.86 mmol) of the product of Example 28 in 10 mL of DMF was added 0.14 g (3.57 mmol) of 60% sodium hydride. The resulting mixture was stirred for 30 min at room temperature and then 0.42 mL (3.57 mmol) of benzyl bromide was added. This reaction mixture was stirred overnight at room temperature, poured into water and then extracted with ether. The combined organics were washed with water and brine, dried over MgSO4, filtered and concentrated in vacuo to provide a white solid which was recrystallized from ethyl acetate (EtOAc)/Hexanes to provide 1.084 g (85%) of the desired product as a white solid. Electrospray Mass Spec: m/z 428.3 (M+H)+.
