Reaction Steps

To the product of Example 200 (200 mg, 0.00033 mole) in DMA (1.5 mL) was added carbonyldiimidazole (67 mg, 0.00041 mole). The reaction was stirred at room temperature for 1 hour. Tetraethyleneglycol (214 mg, 0.0011 mole) was then added and the reaction mixture was stirred overnight at 60° C. The reaction was cooled to room temperature and the product was isolated by RPHPLC to yield the title compound (120 mg after lyophilization) as a hygroscopic white solid. MS and NMR were consistent with the desired structure.
