実験手順
A mixture of (3-bromo-quinolin-6-yl)-acetic acid hydrazide (prepared according to procedure described herein) (4.12 g, 14.7 mmol), cyanogen bromide (1.1 eq., 16.2 mmol, 1.7 g) and KHCO3 (1.25 eq., 18.3 mmol, 1.83 g) was stirred in methanol (30 mL) at ambient temperature for 18 hours. The was then diluted with water (40 mL) and the solid was collected via filtration and washed with cold methanol and dried to return the title compound as an off white solid (4.02 g, 13.2 mmol, 90%). 1H NMR (DMSO-d6): δ 4.27 (2H, s), 6.94 (s, 2H), 7.71 (dd, 1H), 7.86 (d, 1H), 8.02 (d, 1H), 8.73 (d, 1H); 8.93 (d, 1H); MS (m/z) 305 [M+H+]+.
