The title material of Example 17 (100 mg, 0.00025 mol) was dissolved in DMF (2 mL), and to the solution was added 2-Chloronicotinic acid (40 mg, 0.00025 mol), HATU (144 mg, 0.00038 mol), and DIEA (49 mg, 0.00038 mol). The reaction was blanketed with argon and stirred at room temperature for 18 hours. The solution was concentrated in vacuo, and the resulting solid were washed with water and then filtered. The product was then recrystallized from ethanol, and isolated by vacuum filtration. 25 mg. (MW=530.93, 19% yield). LC/MS m/z=531.7 (m+1).
