반응 단계
Morpholine (871 mg, 10 mmol) and N,N-diisopropylethylamine (2.6 g, 20 mmol) were added to a solution of 3-(4-chloro-7H-pyrrolo[2,3-d]pyrimidin-5-yl)benzonitrile (C14) (2.5 g, 9.8 mmol) in n-butanol (100 mL), and the reaction mixture was heated at reflux for 3 hours. Solvents were removed in vacuo and the residue was purified using chromatography on silica gel (Eluent: 1:1 ethyl acetate/petroleum ether). Subsequent recrystallization from ethyl acetate and tert-butyl methyl ether afforded the product as a white solid. Yield: 770 mg, 2.52 mmol, 26%. LCMS m/z 306.0 [M+H+]. 1H NMR (400 MHz, DMSO-d6) δ 12.34 (br s, 1H), 8.41 (s, 1H), 7.99-8.02 (m, 1H), 7.89 (br d, J=8 Hz, 1H), 7.76 (br d, J=7.5 Hz, 1H), 7.71 (s, 1H), 7.68 (dd, J=7.8, 7.8 Hz, 1H), 3.44-3.50 (m, 4H), 3.11-3.17 (m, 4H).
