Procedure

Ethyl 3-(3-chloro-5-{5-[6-(methyloxy)-3-biphenylyl]-1,2,4-oxadiazol-3-yl}-1H-indol-1-yl)propanoate (D107) (90 mg, 0.18 mmol) was heated in ethanol (10 ml) to give a clear solution. This solution was treated with 2N sodium hydroxide (3 ml, 6 mmol) and stirred at 50° C. for 30 minutes. Evaporated off the ethanol and filtered off the white solid that precipitated out of solution, washing the solid with a small amount of water and ether. Stirred solid in a small amount of acetone for 1 hour, filtered, washed with a small amount of ether and dried to yield the title compound as 45 mg of white solid. δH (400 MHz, d6-DMSO) 2.34 (2H, t), 3.91 (3H, s), 4.34 (2H, t), 7.41-7.46 (2H, m), 7.48-7.50 (2H, m), 7.57-7.59 (2H, m), 7.63-7.66 (2H, m), 7.80 (1H, d), 8.10 (1H, d), 8.10-8.25 (2H, m). MS (ES) C26H2035ClN3O4 requires 473; found 474 (MH+).
