실험 절차
A mixture of diethyl malonate (24 g, 0.15 mol) and 2,4-dichloro aniline (60.8 g, 2.5 eq) was heated at 200° C. upon passing nitrogen gas stream to distil out ethanol. Six hours later, the reactants were cooled to room temperature with adding diethylether. The solids produced were filtered and washed with diethylether (yield: 48 g, 82%): 1H NMR (CDCl3) δ10.04 (s, 2H) 8.04 (d, J=9 Hz, 2H) 7.42 (m, 2H) 7.26, (dd, J=2.4, 9 Hz, 2H) 3.74 (s, 2H)
