実験手順
Using the same general procedure as described for the preparation of 226b, reaction of 3,5-dibromo-1-methylpyridin-2(1H)-one (1.51 g, 5.65 mmol) with 5-(1-methylpyrrolidin-2-yl)-2-amino pyridine (1.00 g, 5.65 mmol) gave an 81% yield (1.65 g) of 229a as a yellow solid: mp 143-145° C.; 1H NMR (300 MHz, DMSO-d6) d 8.73 (s, 1H), 8.68 (d, 1H, J=2.4 Hz), 8.15 (d, 1H, J=2.1 Hz), 7.55 (dd, 1H, J=8.9, 2.1 Hz), 7.52 (s, 1H), 7.30 (d, 1H, J=8.9 Hz), 3.52 (s, 3H), 3.13 (t, 1H, J=7.5 Hz), 2.99 (t, 1H, J=7.5 Hz), 2.19 (m, 1H), 2.10 (m, 1H), 2.05 (s, 3H), 1.79 (m, 2H), 1.71 (m, 1H); MS (ESI+) m/z 363.3 (M+H).
