実験手順
Sodium hydride (60% in mineral oil, 9.14 mg) was added to a solution of 1,1-dimethylethyl 3-[7-(5-{3-cyano-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1H-indol-3-yl]propanoate (D9) (120 mg) in dry DMF (5 mL) at RT. After stirring for 5 min, iodomethane (0.032 mL) was added. The resulting solution was stirred at RT for 15 min, then 1 hour more. EtOAc (50 mL) was added and the resulting solution was washed with saturated aqueous sodium bicarbonate solution (50 mL), followed by water (50 mL). The organic fraction was dried over anhydrous magnesium sulfate. The dried solution was concentrated. The residue was purified by Biotage (25% EtOAc in hexane) to afford 1,1-dimethylethyl 3-[7-(5-{3-cyano-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-3-yl]propanoate (D10) (60 mg) as a pale yellow oil. MS (ES): C28H30N4O4 requires 486; found 487.0 (M+H+).
