실험 절차
[(2-Bromophenyl)-hydrazono]-cyanoacetic acid ethyl ester (15.28 g, 51.60 mmol) was dissolved in 40% methylamine in water (67.5 mL) and stirred at room temperature overnight. The reaction mixture was concentrated to dryness, slurried in diethyl ether, and filtered. After drying under high vacuum at 40° C., the title compound was obtained as a yellow solid (11.16 g, 77%). 1H NMR (300.132 MHz, CDCl3) δ 7.68 (dd, J=8.2, 1.4 Hz, 1H), 7.54 (dd, J=8.1, 1.3 Hz, 1H), 7.35 (t, J=7.9 Hz, 1H), 7.01 (td, J=7.7, 1.5 Hz, 1H), 6.29 (s, 1H), 2.98 (d, J=4.9 Hz, 3H). MS APCI, m/z=281/283 (M+H). HPLC 4.08 min.
