実験手順
Staring from 4-bromopyridine hydrochloride (16) (356 mg, 1.83 mmol) and compound 17 (400 mg, 1.52 mmol) title compound 18 was obtained (398 mg, 77% yield) according to the known procedure (Harris, M. C.; Geis, O.; Buchwald, S. L.*; J. Org. Chem., 1999, 64, 6019-6022). 1H NMR: (DMSO-d6) δ(ppm): 8.58 (d, J=6.5 Hz, 1H), 8.18 (d, J=6.5 Hz, 2H), 7.72 (d, J=8.8 Hz, 2H), 6.91 (d, J=6.8 Hz, 2H), 6.58 (d, J=9.0 Hz, 2H), 4.46-4.40 (m, 1H), 3.71 (dd, J=10.6, 6.3 Hz, 1H), 3.48 (dt, J=9.6, 7.6 Hz, 1H), 4.42 (td, J=9.8, 4.9 Hz, 1H), 3.27 (dd, J=10.4, 3.3 Hz, 1H), 2.35 (sext, J=7.2 Hz, 1H), 2.05-1.98 (m, 1H), 1.50 (s, 9H). LRMS (ESI): (calc) 339.19 (found) 340.2 (MH+).
