Reaction Steps

To a solution containing 150 mg of the product from Example 38 (0.51 mmols) in 2.6 mL of dry DMF was added 25 mg of NaH (0.61 mmols, 60% suspension in oil). After stirring at ambient temperature for 5 min, 0.033 mL of chloroacetonitrile (0.51 mmols) was added to the reaction via syringe. The reaction was warmed to 60° C. for 16 h. After cooling to room temperature, 1 mL of water was carefully added to the reaction mixture. The mixture was diluted with 20 mL of EtOAc and washed with 2N NaOH (3×10 mL). The organic layer was dried over MgSO4, filtered, and concentrated in vacuo. The residue was dissolved in a minimum volume of DMSO and filtered through a 0.45 m acrodisc filter. The resulting solution was purified on the Gilson reverse-phase HPLC to afford the title product (4 mg, 2%). MS (ES+) m/e 334 [M+H]+.
