실험 절차

A solution of ethyl 3-[5-(5-{5-chloro-6-[(1-methylethyl)oxy]-3-pyridinyl}-1,2,4-oxadiazol-3-yl)-1H-indol-2-yl]propanoate (D115) (112 mg), dimethyl carbonate (2.0 mL) and DABCO (33 mg) in N,N-dimethylformamide (2 mL) was stirred at 90° C. for 2 days. After cooled to room temperature, the reaction mixture was diluted with ethyl acetate. The organic solution was washed with water. The organic solution was dried over anhydrous sodium sulfate. The dried solution was concentrated. The residue was purified by column chromatography to afford methyl 3-[5-(5-{5-chloro-6-[(1-methylethyl)oxy]-3-pyridinyl}-1,2,4-oxadiazol-3-yl)-1-methyl-1H-indol-2-yl]propanoate (D116) (72 mg). The crude product was used directly in the next step without further identification.
