실험 절차

A mixture of crude trifluoromethanesulfonic acid 1-(4-methoxy-2,6-dimethylphenyl)-3,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-4-yl ester (1.1 g), N,N-diisopropylethylamine (0.65 g) and piperidin-4-yl-acetonitrile (1.6 g) was heated at 150° C. in a sealed tube for 7 hours. After cooling to room temperature, ethyl acetate and water were poured into the mixture, and separated. The aqueous phase was extracted with ethyl acetate, and the organic phase was dried over MgSO4 and filtered. The filtrate was concentrated under reduced pressure and the residue was purified with column chromatography (silica gel: Wako gel C200, eluent: hexane:ethyl acetate=3/1) to obtain {1-[1-(4-methoxy-2,6-dimethyl-phenyl)-3,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-4-yl]-piperidin-4-yl}-acetonitrile (0.58 g) as a pale yellow crystal.
