실험 절차

To ethyl 3-{3-chloro-5-[5-(3-chloro-4-hydroxyphenyl)-1,2,4-oxadiazol-3-yl]-1H-indol-1-yl}propanoate (D108) (180 mg, 0.40 mmol) and K2CO3 (138 mg, 1.0 mmol) in dry DMF (5 ml) was added isopropyl iodide (85 mg, 0.50 mmol) and the mixture stirred at 80° C. for 30 minutes. Cooled mixture and added EtOAc (50 ml). Washed with water (2×50 ml) and dried over MgSO4. Evaporated off the solvent and crystallised from ethanol to yield the title compound as 120 mg of white solid. δH (400 MHz, d6-DMSO) 1.12 (3H, t), 1.37 (6H, d), 2.91 (2H, t), 4.02 (2H, q), 4.50 (2H, t), 4.89-4.98 (1H, m), 7.72-7.85 (5H, m), 7.95-8.00 (1H, m), 8.24 (1H, d). MS (ES) C24H2335Cl2N3O4 requires 487; found 488 (MH+).
