Versuchsvorschrift

A mixture of 2-(4-(2-methylpyridin-4-yl)phenyl)-N-(5-(piperazin-1-yl)pyridin-2-yl)acetamide 131-1 (39 mg, 0.10 mmol), Cyanogen Bromide (13 mg, 0.12 mmol) and Potassium Carbonate (28 mg, 0.20 mmol) in DMF (1 mL) was stirred at room temperature overnight. The mixture was poured into water (5 ml) and extracted with ethyl acetate (5 mL×3). The combined organic phases were dried over Na2SO4, and concentrated. The crude product was purified by reverse phase HPLC to give N-(5-(4-cyanopiperazin-1-yl)pyridin-2-yl)-2-(4-(2-methylpyridin-4-yl)phenyl)acetamide 176. MS m/z 413.2 (M+1); 1H NMR 400 MHz (MeOD) δ 8.39(d, 1 Hz), 7.96(s, 1H), 7.89(d, 1H),7.68(d, 2H), 7.58(s, 1H), 7.50(d, 1H), 7.46(d, 2H), 7.37(dd, 1H), 3.74(s, 2H), 3.35(t, 4H), 3.18(t, 4H),2.55(s, 3H).
